program not a valid Win32 application

Question: program not a valid Win32 application

I'm troubleshooting a Windows XP (SP2) eMachine (with a fresh OS install on a new hard drive - no original eMachine software remains on the system) and I've never encountered such a persistent problem: certain applications (Fruit Loops, Adobe Acrobat Reader, among others) run fine after installation, but after a reboot they will not run. Their shortcuts, as well as the actual program executables, lose their original icons and are mysteriously changed to the generic window icon (the one Windows will use for a file type is doesn't recognize.) When I try to run these programs, using the desktop shortcut OR the actual executable, I get the error dialog box: "This program is not a valid Win32 application." This happens to several applications, while others (Pro Tools, Acid) remain unaffected and can be executed w/o any problem.
*Note: this computer is not connected to the Internet, so it is unlikely that this is some type of virus.

What could be causing this? Any suggestions are greatly appreciated.

Preferred Solution: program not a valid Win32 application

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

My family computer is a desktop PC running Windows Vista with McAfee. I make sure to run all updates ASAP. My updates are current through yesterday. When I tried to update my computer this morning, the updates failed with an unknown error. "Error(s) found: code 80070103 Windows Update encountered an unknown error"

This morning, I turned on the computer to find that McAfee has been disabled, Windows Defender has been disabled, and that I cannot turn them back on. Additionally, I cannot run any programs. Invariably, I get the response "program.exe is not a valid Win32 application" regardless of whether I run the program from the C drive or a USB.

Neither Internet Explorer nor Firefox are working; I can only access the internet by opening windows explorer and typing an address into the address bar in that window.

I have tried running McAfee in safe mode, but get the same message. I tried the "repair computer" function when I boot the computer, but it insists that I have another drive attached (though I have unplugged the camera, flash drvie, external hard drive)... There is nothing attached (except for the keyboard and mouse). I have tried restoring my computer to a previous restore point only to be told by the computer that there are no restore points.

I started Googling and thought that it may be the Bagle virus because of the "is not a valid Win32 application" but found none of the files listed on the Removing Bagle Infections page... Read more

Hi I have been having problems lately with System Restore, Magnify, and WordPad (the only ones i have noticed so far) that when I start them they give me an error stating they're "not valid win32 application(s)". I was able to fix my system restore by opening command and doing a 'SFC /SCANNOW' scan. I was wondering if there is anythig else I can type in command to hopefully fix the other two programs? Or are there any other solutions to this problem?

I need to install eclipse classic by Monday. I installed it about a month ago with no problems but didnt use it for a while.

On Friday I clicked on its icon and it wasnt working, I wish id taken note of what it said but I think it was something to do with not being able to access a file.

Its probably worth mentioning that you cant actually uninstall eclipse. Theres no uninstall option so you have to search for eclipse and then just delete all the files you get.

I downloaded it from the website( again. It comes in a zip file. I unzipped it and I was pretty sure that it looked different already. The eclipse.exe file had the eclipse icon as its image the first time I tried to install it (or atleast im pretty sure it did) and now its that white square with a blue frame thing (looks kinda like a 2D oven). I click on it. It asks me if I want to extract all or run. I have taken both options and they both lead to the same conclusion; a message saying "blah/blah/blah/elipse.exe" is not a valid win32 application.

I have tried to deal with it in the following ways:
I downloaded the windows 64 bit version. This led to the same result.
I searched for eclipse and deleted everything that came up. Then I downloaded it again and repeated the process. This led to the same result.
I scanned for virusess with spybot, norton and avast and got none.
I defragmented the disk on the advice of the internet.

OK, this is admittedly a strange one...

I have used an old (probably a 16-bit) application as my time synchronizer this I've used for quite some time. Its name is TimeRC, and is a great synchronizer as it tracks moon phases along with the time (from selectable, multiple potential time servers). After a fatal software crash a couple of weeks ago, I'm in the process of recovery. Attempts to manually launch the EXE, result in a launch-time error stating that the ap is not compatible with my Windows 7 Pro (SP1). Note that I'm running on the same level of Windows that I was using prior to the crash/re-install. I have inhibited compatibility checking (Group Policy adjustment) only to incur the Win32 error.

I've been through the litany of utilities (registry) to correct this situation, and I KNOW that this ap runs just fine on Windows 7 (from pre-crash days). I am at my wits end trying to avoid this situation. I suspect that there is a registry setting difference (now versus pre-crash) about which I'm ignorant, so I'm open to any, and all suggestions.

To use an alternative time synchronizer is not an option...I'm anal about how my system looks, feels, and performs!! I've even tried running in XP mode (virtual machine) to no palatable result. Note that I don't have access to the program's source code, otherwise I could recompile!

There's got to be something that I'm missing.

Hi everybody.I have came upon a slight problem.I have just recently fixed my brothers computer,and he now has a small problem.He plays a game called Freestyle Street Basketball.He told me he clicked on the game,and it started updating.Well,the update froze,so he went into the task manager and went under processes and ended the process on the update.(Update was running under admin.) Is there anything i can do besides reinstalling it? He told me it takes forever,and he would like to avoid that process. Btw. The program and its files have no viruses.Downloaded from a trusted source,and just checked with webroot.

Answer:Not a valid win32 application

It would be worth the wait to re-install it...then re-boot and grab the update.He can't play it now anyways so the lengyh of time it takes to re-install shouldn't matter anyways.

For some reason, whenever I attempt to click my D:\ drive to use the CD i put into my computer, the message "D:\ is not a valid Win32 Application" comes up and nothing happens. This has never happened before, and I just had a massive overload of viruses, so I'm assuming it has something to do with viruses affecting my computer. And I'm pretty sure its not my CD that has the problem, since I tried another CD and it showed the same error. Does anyone know of a way to run my CD? I only need to run it once (I'm attempting to run the Windows XP CD to completely wipe my computer since its becoming very bad). My computer is an hp intel pentium 4 with 512 mb of ram (yes i know it sucks) with windows SP2EDIT: I found the answer...It seems that both disks were infected.

Answer:not a valid Win32 Application

Did this happen to Ad-aware before or is this your first time running Ad-aware? If this is the first time, try reinstalling Ad-aware.

Otherwise, I would check for any viruses/trojans:

If you have a fast internet connection (broadband), run an online virus scan at TrendMicro. Just follow the instructions on the site to run the online scan. Otherwise, make sure your antivirus program has the latest definitions and run a full system scan.

Answer:HELP not a valid win32 application!!!!!!!

Sounds like the zip have have is having the wrong extension, check your Folder Options in windows and make sure that extensions are not hidden, and then check that the zip-file in question has .zip as extension.

Another possibility is that the program used for opening ZIP-files have become damaged(By virus/HDD failure or similar) and it is no longer able to start properly. Reinstall the program used for opening ZIP-files.

Instead of double clicking the file, then start either of the following programs 7Zip/WinZip/WinRar/WinACE and open the zip-file through the user-interface of the program in use.

My machine locks up when the screensaver goes on (it's an old one with the two animated guys from Guinness, who go "Drink beer straight from the bottle?! BRILLIANT!" - the screensaver, not the computer). So I restarted it. I've had to do this a few times over the past few days. So today I tried to open Firefox, and it didn't work. I tried to open anything, GOMplayer, Winamp, none of the shortcuts would work, they all came back with an error message saying they're not valid Win32 applications. I tried typing in Firefox.exe into the Run prompt on Task Manager, but that had the same result. Finally, I typed a URL into the run prompt, and it brought up Firefox. I downloaded Avira, but when I tried to install it, the error message popped up that it's not a valid Win32 application.

Interestingly enough, I the path to a JPEG saved on my computer into the Task Manager just like I did with the URL, and it opened right up in Windows Picture And Fax Viewer. Video files bring up WinAmp, and spreadsheets bring up Excel, and yes, these I have all these set as the default programs for these types of files. So programs themselves will run, but I can't start them myself, for some reason. How can I fix this?

Answer:Nothing will run, nothing's a valid Win32 application.

Try a System Restore.

Mbam.exe wouldn't launch, though it would display in the list of active processes under the ctrl+alt+delete menu. After Googling the issue (and winding up here), I decided to try renaming MBAM.EXE to MABM.BAT. This worked, I found ~150 infected objects, and cleaned them without really looking them over.

This seems to be a Microsoft problem that has been around for years, according to all the info I've found with Google, but none of them explains or solves the problem I've got.

The machine (owned by a friend) is running Vista (Home Premium) and the problem is initially with Word 2000. I've been looking round this machine with the following results.

Double clicking on ANY .doc file gives the error message saying that it is not a valid Win32 application. Well, of course, it isn't; it's a word document file.

The file associations all look OK (and I've been through all attempts of 'Open With...') and using assoc gives .doc=Word.Document.8 and ftype gives word.document.8="c:\Program Fi.....\WINWORD.EXE" /n (there's no /dde which I have seen mentioned elsewhere - is that relevant?). Even the .doc file is showng with the Word icon.

I've done a repair install on Off.2000 with no change and I've uninstalled it and reinstalled it from scratch - still no change.

I CAN open the file normally from with Word and I can open it by dragging it and dropping it on a shortcut to Word, I just can't get it to obey the file association.

Excel 2000 shows the same behaviour with .xls files and so does Word with .dot files.

Other associated files opening other programs seem to work OK (.jpg, .pdf, etc).

Everything was working fine a week ago and there hasn't been any Microsoft update during that period.

Answer:.doc is not a valid Win32 application

I had similar problems with .doc files after running Vista for the first time.
The fact was that the files were on a networkdrive which I use with my family, (Windows XP and Windows 98).
I first copied the file to my local HDD and then it opened and I saved it back and it worked.
Reason? MS for sure, but no solution.
Now I am still running W7 RC1 (full version still waiting to be installed) and no more problems even with older files.

Answer:not a valid Win32 application

When you ran MGTools.exe, did you get any error messages? Did you fail to agree to the user license for HJT?
If you did get an error message, see this: Using MGtools

Let's also do this:

Open notepad and copy and paste the following text in the quote box into the window:

sc stop srosa
sc delete srosaClick to expand...

Save this as fix.bat
Choose to save as all files.
Doubleclick fix.bat and let the program run.
A small black dos window will flash, this is normal.

Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

I have just recently run into a serious problem with my web browser. I have been unable to download anything of value due to some sort of corruption. I tried to download the free version of Firefox Mozilla and at the end of the download when I tried to run the installation wizard I got the message sys exe is not a valid win 32 application. I then tried download the application to a cd and install it from the disc and I got the message "file is corrupt". I assume that something is wrong with my IE 8 because just before Christmas the laptop started to slow down drastically, and an automatic update for my Norton Internet Security 2006 was unable to download on the first try, and when I was prompted to restart and try again the entire program just disappeared. As a matter of fact, in the dialogue box of any download everything is listed as taking up to as long as 23 hours. Do I have a virus or is there something else sinister going on here?

Answer:sys exe not a valid win32 application

sys.exe is malware. Your computer is most likely infected. Therefore, please click on the Report button and kindly ask to be moved to the Malware Removal forum.

Hi all, I have a Pentium IV 524 (3.06 GHz 1M L2 533FSB) NEC Powermate ML7 Q8200; with XP Home Edition.

For a little while I have been getting the message " is not a valid win32 application" on start-up. You just have to ok that message and then it proceeds fairly normally. One thing it does do is overheat? i.e. it seems to be working extra hard (right from boot-up) and eventually seises up. To this end I installed a 1Gig RAM card the other day (it now has 1.5 Gig). That helped a bit but of course the message still comes up.

I googled the message and from this site learned that it is indicative of a virus. It instructed me to locate the file in the System 32 folder and delete it. I found 4 cmd type files in the folder. I right-click/Properties the 4 files: 3 seemed legitimate and had no mention of the dot-com. They were all 'Application' or 'application extension' type files with the description in black print. One seemed suspect; it was called cmd; type was MS DOS Application, print in blue, had a size of zero and right-click/properties showed -under program- that it had a cmd line: C:\WINDOWS\system32\ I thought that this must be it and so removed the file to the trash.

After that the computer functioned very slowly. The Windows Task Manager/Processes showed that the were only about 20 processes running instead of the usual 50 or so (approx).

I've spent the last two days trying to figure out whats going on. I have Windows 7 Premium, 64 bit system and removed the CA Total Defense Anti-Virus program because it wouldn't allow my email to load into Thunderbird. Plus it seemed to be causing problems on my system from the beginning (about 2 mos). I wanted to go back to the Microsoft Security Essentials and when I tried I got the message;

mseinstall.exe is not a valid Win 32 application

I also removed a program called My paint because I couldn't get some brushes to load into the program. I tried to reinstall the proggie thinking maybe it had just been corrupted. But I get a similar error message;

mypaint-1.0.0_win64_installer.exe is not a valid Win32 application.

I have managed to Avast Free anti-virus installed and ran a full virus scan which came up clean. I also ran Malwarebytes that cleaned out some garbage, and I also ran my Super AntiSpyware which also cleaned up a few things.

At this point I'm at a loss and wondering if there could be a hidden Trojan or possible the registry is messed up from whatever was on the system. Can you please advise? I need to get the My Paint program back on because it's used on a regular basis. But I also don't want to be just limping along waiting for other issues to crop up.

Thanx for any help,

Answer:Not a Valid Win32 application

This is an error typically found with a corrupted dfile from a download, however it sounds like you were infected at one point. Be sure you do FULL scans and not basic with Superantispyware and Malwarebytes. Clean your junk files with CCleaner.

If no luck maybe Windows Repair can restore a busted setting. Removing malware does not always fix something that was broken in Windows from that infection.

Answer:not a valid win32 application

Is your OS Microsoft Windows XP 64-Bit Edition and maybe you're attempting to install a 16-bit program?

When you attempt to install a program on a computer that runs Windows XP for 64-bit platforms, you may not be able to do so, and you may receive one of the following error messages:

Install.exe is not a valid win32 application.

Setup.exe is not a valid win32 application.

This behavior can occur if the program you are trying to install uses a 16-bit Install.exe or Setup.exe file. By design, Windows XP for 64-bit platforms does not support 16-bit programs.

Welcome to Major Geeks!

Let's see if we can get some info so that we can determine which system file has been corrupted. That way we can try to replace it.

Download and save the below to your PC (save it anywhere you can find it. The Desktop is fine). Then double click on it to run it.


It should take a couple minutes to run. You will see a black command prompt window while it is running and it should close when it is finished. Once it finishes, attach the c:\avplog.txt
Now download and Run exeHelper

Please download exeHelper to your desktop.
Double-click on to run the fix.
A black window should pop up, press any key to close once the fix is completed.
Post the contents of log.txt (Will be created in the directory where you ran
Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file)
Next, try running the below online scan:

Reboot immediately after scanning if it finds and removes anything. Let me know if anything was found. See if you can save a log with it and attach it in the next reply.

Now run a scan with MGtools and attach the log. Using MGtools

Next post please attach:

log.txt (from exeHelper)

Check the file size it's probably less than 10k, it should be almost 1meg.

Try again at the website, this time by right clicking the download link and Save Target As.

I've emailed the author and asked if he could make a zip version available at his site. Sometimes Executables get chewed up travelling around the net.

If it's still a problem and you have XPSP2 then you might have to list drivershaven as a trusted site in IE security.

Let me thank you up front, you've helped me with a few issues similar to the one I'm describing here.

My son's computer runs fine, but he thought his computer may be infected, and it seems it is. Avast has picked up a few files associated with Antivirus 2006, 2007 etc... according to the filename searches on the internet. His computer seems to run fine for games like (WoW, Call of Duty etc..), internet and whatnot. It shuts down slowly if at all and that's a problem, but that's the only problem we've seen.

Anyway I ran Avast and up popped warnings of VIRUS and ALERT. I moved the files in question to the chest, but soon decided I needed professional help. So here I am.

One of the first things I read was NOT to do anything if the antivirus program finds anything, so I'm tell you now I did move some bad files to the Avast chest like I said above. But that's all I've done.

According to your instructions I should first run the dss download, but I get an error "cmd is not a valid win32 application" . I searched a few forums about this error, but I'm still unable to find the cmd file and I've even searched for hidden files and folders in the WINDOWS directory. So I dont know how to proceed.

Hi, ok first off all im swedish so i dont know very much english.
Ok, so I'm coding in a program called "Pawno" (a pawn editor)
Pawno is used for GTA San andreas multiplayer, Called SA-MP.
When i try to open a script with Pawno it just says: C:\Dockuments And Settings/Oscar/My documents/script/LARP.pwn is not a valid Win32 application (.pwn is in association with Pawno) And same goes when i try to compile a script (from .pwn to .amx)
The thing is, I can open Pawno and from Pawno open the .pwn file, but cant open the .pwn file first.
When i take another GTA san andreas script program and compiles it says:
>%l is not a valid Win32 application.
And at last pawno uses a separate compiler named pawncc.exe, wich exists in my pawno folder.

Anyone please help!


Answer:is not a valid Win32 application

XP does not recognize "Pawno" as a valid Win32 Application. You can open files from within Pawno, but you cannot launch Pawno by double-clicking an associated file.

This sounds like normal behavior for XP. Meaning that if there is a problem, the problem is with Pawno and not XP.

Do you know of anyone else that is able to launch Pawno by double-clicking on an associated file ? If not, I would think the issue would be best addressed to the manufacturer/author of Pawno, and the defect may lie there.

However, in general, uninstalling and then reinstalling applications frequently fixes a lot of problems.

I can't open my photos or pictures anymore because it keeps saying 'JPG is not a valid win32 application'. It never used to do this so I'm sure I've done something wrong. I have tried for ages to fix this on my own but I can't. Please can you help me?
Thanks in advance

Answer:JPG is not a valid win32 can I fix this?

a *.jpg file opening gives a not vallid file error

solution to this is that the link in windows informs windows to open *.jpg with a program that is not correct win32 openable .

2 possible common causes.
the link is wrong
the file is wrong
for instance if you have extentions hidden , something could be displayed as namehere.jpg
what you wouldnt see is namehere.jpg.scr
and that would be a virus , but mostly people are warned enough about those nasty things so they have virus protection , and if that would have been the case your virus scanner would of had a busy day :)

so picking the first possible cause , the wrong link
easy enough you can right click on the jpg file and you can then select " open with " rollout menu to the side then the option open with if im correct wich causes a dialogbox to pop up informing you of a list of all the software programs currenly active installed in windows.

jpg file i would prefer to open with something that always works and normally present in windows either windows imaging ( wich is in the list ) or MS paint . both should work .
later on when you have the hang of this you can obviously change it to photoshop ect ect.

hope this helps .

Hey, i have a very annoying problem and i hope you could help me!

Since yesterday, everything i download and try to open is "not a valid win32 application", while all archives i try to open are "either in unknown format or damaged"(archives that i download), and every torrent i download is not a valid torrent file!

i can open everything except the files i downloaded yesterday and today.

i read about a bagle, or beagle or something like that. i was thinking it might be it, or just another stupid bug

i'm using 32 bit vista home premium 6 build 6001

the files i tried to open are definitely not corrupted! i tried to download vuze, a new version of msn, about 20 different torrents and so on. nothing works.

also another thing i noticed, is that sometimes firefox stops at 3 kb/s or 2 kb/s and just freezes the download. i wonder if it's related?

Hi, I'm just new to these forums and am having some terrible problems with my computer, so please bear with me and give me some support

Upon downloading an application I found that when I click on the download and select "Run" I get the message "XXX.exe is not a valid Win32 Application" XXX of course being the name of my download, not an actual file name. My antivirus is also somehow missing. This of course also means that I can't download a new antivirus or any program to attempt to fix my computer, so I may have to rely on a completely manual method of repair.

I have also found that when I save an image its download size is 0kb, another major problem =/

Please give me some advice about how to rectify this problem, preferrably one that does not involve resetting to factory defaults as I have misplaced the recovery disks.
Thanks in advance =D

Some information about my computer:
OS: Windows Vista Home Premium
Model: Toshiba Equium A210
Processor:AMD Turion 64 X2 Mobile Technology TL-60 (2CPU), ~2.0GHz

Hi everyone, recently a Kaspersky AV false positive detected regedit.exe as a trojan and decided to quarantine it. I was able to recover it from quarantine and restore it, but since then I cannot merge ".reg" files with my registry. I get the message that *.reg (where * is the current file im trying to merge) is not a valid win32 application. Is there any way I can fix this? Or restore the original regedit.exe files as opposed to those recovered from quarantine?

Cheers, Matt

This is what happens when a friend attempts to install Corel v.12 from the original CD.
If he places Disk 1 in the drive it shows a Corel logo and then spends ages with the "spinner" before showing the title error message - E:\ is not a valid Win32 application.
He must be doing something wrong!
I would guess that he is doing something like a double click before the software has had a chance to spin-up by itself.
Any idea much appreciated.

Answer:E:\ is not a valid Win32 application

Site thinks that a link that I was going to post is spam! Basically it's an installation problem caused by a registry error or malware (unlikely from a CD) or a conflict with something else that is running. Try installing without anti-virus on.

Trying to download Burger Island 2 from, who I never have problems with. At first my virus protection AND my computer were stopping me from launching it. I threw it on the safe list on my virus protection, I have made sure I have all the Windows Updates and have cleared my temporary files. Still no joy. When I go to play the game, I get that the file is not a valid Win32 application. Any tips?

Answer:Not a valid Win32 application

Well, judging by your "OS:" field, under your profile; it says you have a x64-bit OS, meaning you can't run a x32-bit program file, so the alternative is to find a x64-bit installer of your video game.

Could you give me the link to where you're downloading your video game from (not, but the actually link to where you're clicking "download" and it shows you the download dialog) this would help me find it for you and it would save you time.

This is not a malware problem so I'm moving it to the Software Forum.

You may have just lost the file associations for jpg files. Inside Photoshop you should have an option/setting somewhere to setup File Assocications. Make sure Photoshop is associated with jpg files (and any other files you want it associated with).

The subject title really say's it all. I have gotten this message several times when trying to run certain new applications. For instance, my Canon creative home and printer Cd just won't run. I alway's get error's when I start it up. I was able to go to Canon's home page and dload the driver I needed to run my printer, but I have no access to any of the Printing Progam's like American Greeting's and Crayola and all of that. My Canon application is just one example. This error has also occured when trying to run certain game's and other applications. If auto run does kick in half way through dload from disc it will say, "This file is corrupt or missing" It goes on to say " "This program has performed an illegal" etc..

My question is two fold. An possible explaination for this would be great and a cure to the problem would be awesome! If it is a dll file I need please let me know. I've alway's found the answer's to my computer problem's via this board and am alway's appreciative. Not once has the advice been wrong. Thanks in advance for the help.

Yes I do have an updated virus scan so any dloads for dll's will be scanned for potential viruses. Thanks again! Mark

Do you have access to another PC you can try the CD on? Most of the time that error indicates one of two things. Either the CD is bad or your CD drive is an older drive. If the CD does the same thing in another PC then it's the CD. If it does not, then it's more than likely your CD rom drive.

I am trying to install a program and the setup file won't run. I get a message that says "Setup.exe is not a valid WIn32 application."

I've scanned it and it contains no viruses and I'm not sure why it won't run. Does anyone have any ideas?

Answer:a non-valid Win32 application

It may be damaged or it's possible that the file is not really "setup.exe" but something else that was accidentally renamed. Where did you get it from? Go back to the source (to the CD, web site, or wherever) and grab it again.

Okay, so here it goes. I recently installed my new motherboard (Intel D945GTP), new memory (1 gig DDR2), and a new video card (GeForce 6600 OC 512MB).

I have everything else working fine on my computer (had an issue with drivers before), except my DVD-ROM. I'm using an LG HL-DT-ST 4521B 52X DVD-ROM. Every time it tries to autorun any CD, it says D:\ is not a valid Win32 application. I've tried a number of CDs, none work. I've also used 2 other DVD-Rom drives, and I get the same reaction from them. One is a Sony, and the other is a LiteOn. I've also played around with the jumper settings on all of them, to no avail.

I can explore any CD, and I see the files that are on the disc. When I try to run any executable, I get this error: "D:\setup.exe Only part of a ReadProcessMemory or WriteProcessMemory request was completed."

I have googled this a number of times, and still have found no action or workaround that works for me. I've tried copying the files from the D: to my hard drive. Some files will copy, some won't. Particularly executable files won't.

To the best of my knowledge, I have the most current drivers available for all my hardware. If anyone knows ANY reason why this may be happening, I would be forever in your debt.

Thanks in advance,

Answer:D:\ is not a valid Win32 application

Woot. I fixed it. So this is for all those out there who are lucky enough to come across this forum page looking for this answer. Change your cable. That's right. Just change the little cable that connects the ROM to the motherboard. Simple as that.

Hi guys,

I'm in need of some serious help, my computer is acting extremely weird when opening .exe files which it has never done before. Whenever I try to open ANY exe file I've downloaded it tells me the application is not a valid win32 application. Which I don't understand. I've done a virus scan and it found some Trojans and viruses, and I deleted and disinfected and rebooted the computer. I also went into CMD and did a scan that fixed something within the system files after doing a little bit of research on it. It rebooted but still nothing. It gives me the same annoying error. I tried downloading Malwarebytes Anti-Malware but it also gives me the same error as with other setup and exe files. Right now I'm stuck with Microsoft Windows Defender in scanning. I tried downloading from Internet Explorer to see if it was from Google Chrome and still no luck as well. I feel like I'm stuck in a very deep technical error hole. Any help would be greatly appreciated. Thanks for the help.


There might be some viruses left, because the scan did not finish due to the monitor not responding, so I had to shutdown and reboot. But I'll try again and wipe out any more I find if any. not a valid win32 Application....

the viruses screwed up your file associations from the sound of it.
Go to the below linked tutorial and use it to ensure you exe file settings are correct.
Default File Type Associations - Restore
(just scroll down to exe)
it does sound like you've done a decent job of removing the malware, so hopefully all you need to do is fix the association.

This is my first post so I'm likely to appear stupid. I'm of average computer competence but love the things. Short story is this:

I have an accounting program in which I have data files for each year of my business. These have been successfully backed up for years on CD and now JumpDrive, and stored on the desktop with a shortcut for easy access.

I downloaded and installed SP2. Now when trying to open a file, I get the message C:\XXX\XXX\XXX is not a valid Win32 application. It always was before so what changed?

I cannot back up my current files because that is the name I've always used. The computer doesn't recognize the name as valid so I have no security.

An ancillary problem is that years ago, my adorable husband somehow associated my old data file to be opened with MusicMatch. (We don't even discuss this.) I managed a workaround so that I got the files to open with their program application even though I could never change the icon from MusciMatch. No harm no foul. No longer. Post SP2, the danged thing went back to opening MusicMatch, ignoring my old workaround. Messing with it for hours got it to where I'm now getting the invalid file messagel

Can anyone help me? These files are serious stuff to me.

(See, I do appear stupid. )

Answer:Everything is not a valid Win32 Application

Your issue is caused by one of the following:
1. File is corrupt, bad, or missing.
2. File is not designed for your version of Windows.
3. File is a virus, worm, or other malware file.
4. Hardware incompatibility.
