Preferred Solution: program.exe is not a valid win32 application error

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.)

Answer: program.exe is not a valid win32 application error

Have you run an up to date virus checker? I ask because the SirCam virus can modify the .exe file association in the registry.

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?

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

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.

Please help if you can!After my son used my computer I noticed two problems which scare me and indicate (I think) a virus problem. First: after typing a Google query, I click onto the desired link and find myself redirected to other search engines which also performed the same search I had just requested from Google.Second: I downloaded the free Ad-awareAE program onto my desktop, but when I clicked on the icon to install it, i got the message "AD-Aware.exe is not a valid Win32 application"Based on some internet searches I made, it seems these are symptoms of virus activity and I am petrified to do any online banking.

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.

All my desktop programs give this error but if I try shortcuts to folders it doesn't. Very confusing so can someone please help me out.

Answer:'is not a valid Win32 application' error

Please try this workaround (you will need your Windows? XP SP2 CD or an integrated SP3 CD if SP3 is installed).

(In the event that you do not have a Windows? XP CD with SP2,(or SP3) you will need to 'borrow' one from a friend or colleague, as the manufacturer's "Recovery Discs" will not work in this instance.)

Insert the Windows? XP CD in your drive. (Hold down the Shift Key to prevent it from starting.)

Go start > Run the box type in sfc /scannow ?please take note of the space between the sfc and the /.

This is the System File will scan all the Windows? core system files to ensure that they are in their respective correct places, and if not replace them from the CD. During the scan you may be asked to Insert the CD, if this happens just go retry and let it do its thing.

One important point: While sfc is running, it is not advisable to do any other work, or have any browsers/programs running on the computer, until the scan is complete. (This process will generally take around 45-65 minutes to complete).

I have read through the other threads that seem to treat similar problems but none of the solutions proposed fits my case.

The problem machine is running Windows XP Media Center Edition Version 2002 with SP 3 (french).

Symptoms :

- Running many applications that previously worked gives me the "file.exe" is not a valid Win32 application error.
- I cannot boot into Safe Mode (the machine just cycles through and reboots), I can only boot into normal mode
- Machine is running slowly although I can't see any "greedy" processes in the Task Manager

I have tried the system restore several times to different points preceding the problem arriving, each time the system said it could not do the restore.

I have been through the Malware removal Guide read-me first and the Cleaning procedure but I still have the same problems. I have run several BAGLE removal tools as Asquared and Malewarebytes' AntiMalware detected this and apparently removed it.

I have uninstalled the Antivirus (Avast) and the malware removers that I had, been through the add and remove programs to remove anything I don't need / can reinstall later.

I have tried installing :

CCleaner / Search and Destroy / Kapersky / SuperAntiSpyware / Combofix.exe

none of them will run : always the "not a valid Win32 application error"

Can anyone help me ? I'm at a dead end.

Thanks in advance,

I have been trying to install a new disk of Office 2003 Prof onto a new Lenovo T400s Win XP Pro laptop and I can't get the cd rom to read the disk consistently.

When I do get the disk to "run" it asks for the product key. After entering that eventually get an error:
Line 12
Char 1
Error .\setup.exe is not a valid Win 32 application
Code 800700Cl
Source WshShell.EXEC

I received a replacement disk and I haven't been able to get that one to run either. When I try to open the first disk, it stops responding. I haven't been able to open the second one at all.

Is there a way to get the device to read new (yet older version) of software. I don't like Office 2007, which is pre-installed though I haven't activated it.

This thing is making me wacko. The virus has taken control. It won't let me delete synchost from taskmgr., it shuts itself off. I can't run regedit, it says has been turned off by Administrator. System restores says not a valid WIN 32 application.

When I go on the internet it shows C:\.......tempie.html. This is the windows police pro file to control my internet. I can't find any reference to Windows Pro or Security Tool on the computer itself by doing search files and folders. But the url always direct to the screen where they want you to buy. I don't want to go back on without being in safe mode that's the only way they can't get in anything. But I'm obviously missing something because I can't open anything to fix anything. I downloaded Fixtm.reg but when I click on it says not a valid Win 32 application. Whatever that mean. So what else can I do. It must be something in my bootlog or somewhere. How can I turn back on regedit. It even was saying to me that system restore was locked. Please your domain administrator. Pulling on hair! So what would be my next step. Thank you Genius.

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 believe it could have something to do with a Virus as my Avast Pro when into "no tamper mode" and it took me 2 days to delete and reinstall it!
First my Desktop Icons and Wallpaper went to blank screen (grey Background is selected) then I did a System Restore and lost only the Desktop Wallpaper Pic without touching anything "usually I think whilst in word" several times At the same time I discovered that my jpeg and jpg files in Win Pictures will not open Says:

I also think that QuickTime is doing something. As a "file re association" or re-associate with QuickTime request box popped up and I clicked yes without realising it and that was when the Desctop Wallpaper went I dont even use QuickTime do I have to have it installed?
can you help please

Answer:[SOLVED] Error bild0043.JPG is not a valid win32 application

Quick Time is attached to iTunes when you download iTunes, you have to download Quick Time also. To change back your pictures to the default program, Right click any .jpg file/Properties/Change button, scroll through the programs and choose which one you want to open the picture with. Default is Windows Picture and Fax Viewer. Make sure the check box for Always use this program to open this type of file is Checked. Click Apply and OK. You may need to do this for .JPEG files too.
You do not need Quick Time unless you are viewing .mov files. To uninstall Quick Time, go to Start/Run and type appwiz.cpl and press enter. In the Add Remove Programs, highlight QuickTime and choose Uninstall.

Hi all,

I am looking for some help..

I have a Fujitsu Siemens laptop which has a built in DVD writer drive.

For the last few months, when I put in DVD disks to install my games, the autoplay does not start the disk up. I open up 'my computer' and the drive is shown with the title of the disk correctly, and it lets me right click and select 'explore'. However, if I try to run the installer from the disk I get the above error message or something similar, i.e. 'D:\ installer is not a valid win32 application'.

Does anyone have any ideas about this. It used to work fine but has not let me install anything for the last few months. Apart from the standard windows updates I have not installed anything new.

Oh, it does still let me play DVD films ok and I can copy files from a DVD disk to the hard drive, it just doesnt let me install games from the disks.

Thanks for any help you can provide.

Hi, I started having problem on my laptop. When I tried to go to microsoft update I got redirected to instead. I have Zone Alarm Security Suite installed which picked up a couple of spy cookies as did Spy Sweeper but nothing bigger or badder, then the laptop started freezing up constantly. I have a new desktop computer now and used an external hard drive to transfer some program setup files. I scanned them first with Zone Alarm and as all seemed safe I loaded them all in. Now, when I try to access my C: drive through My Computer I get the message C:|resycled\ is not a valid Win32 application. However, I can access the drive by right clicking and selecting explore.

Hi there, good folk of Bleeping Computer  :-)  PC, Windows 7 Home Premium, 64 bit.  I have chosen NOT to install the Windows Updates - this may/may not be relevant.  Malwarebytes Free, Avira Pro. I first noticed there might be a problem when I was attempting to download regular definition Updates for Malwarebytes.  The download could never quite complete - it froze up 3/4 of the way through.  Same result after several attempts. I also noticed the internet was running very slowly (and normally it's pretty quick).  Another change in behavior. I uninstalled Malwarebytes using Control Panel.  I also downloaded the mbam-cleaner file from the MB site.  BUT I was unable to open this mbam-cleaner file beyond the Run window (which I clicked), only to get the error message "mbam-cleaner.exe is not a valid Win32 application". Same result when I tried to run rkill - same equivalent error message: "rkill.exe is not a valid Win32 application". Definitly something is awry.  These are very likely to be good files, and something is choosing to block their opening.  I've never seen this error message before.  I have made no changes whatsoever to my registry or startup - nothing at all. Otherwise the computer still appears to be running as it should.  I am writing to you from my laptop. Any wisdom very much appreciated. All warmest wishes,Ralph

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.

First, thanks for reading this. I did read and attempt to go through the steps listed in the Malware Removal Guide. However, although I could download the file for CCleaner, I could not make it run.

I have a new (I've had it for less than a month) HP laptop running Windows 7. I somehow acquired a Trojan, despite having Norton AntiVirus running on my system. I downloaded a few set-up files for programs such as HijackThis and Cleaner7, but I cannot run any of them. I get the "is not a valid Win32 application error" when trying to to do.

I restored my laptop to the original factory settings, but that didn't help. Because I did this, I lost the name of the evil program (I had searched Google for it)... the name sounded something like "animal", and it pretended to find threats on my computer in order to get me to pay for "removal" of them. I tried to remove it in my control panel but of course that didn't work. I thought that since it didn't show up in Programs when I restored it was gone, but I could tell my computer was still infected.

Then you need to work your way through the below

Welcome to Major Geeks!

Please read ALL of this message including the notes before doing anything.

Pleases follow the instructions in the below link:

READ & RUN ME FIRST. Malware Removal Guide

and attach the requested logs when you finish these instructions.

**** If something does not run, write down the info to explain to us later but keep on going. ****
Do not assume that because one step does not work that they all will not. MGtools will frequently run even when all other tools will not.

After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!
Helpful Notes:

If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:

If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware and Malwarebytes ( links are given in the READ & RUN ME) onto another PC and then burn to a CD.

Win 7 Home Premium, new HP laptop, 32 bit, Pentium Dual Core

Installing applications, including ones that say they are Win 7 compatible, I get "not valid win32 application". Letting the system adjust compatibility does no good.

I got Visual Studio 2005 installed with a banner at the end about "compatibility issues", and then got that error on all attempts to update. I've erased that and have ordered VS2010. Instrument drivers that a client will need also give me that error, even though they are supposed to be good for Win 7.

This is my first Win 7 machine, have stayed with Win XP Pro up to now. My client is going to need Win 7. I hate to force him to go back to Win XP mode.

Will I have to upgrade to Win 7 Pro and run in XP mode? Or is there a way to make "compatibility mode" really do something useful?

I don't see anything strange here.

Let's use a program to scan for any trojans that may exist. Download TDS-3. Learn how to use it here. Make sure to update it after you installed it. You can get the manual updates here. When you launch the program, it will scan your memory for running processes. This will take less than 30 seconds. Next go to System Testing on the menu and choose Full System Scan. After that's finished, post the log file by selecting everything on the top pane (select from bottom to top). If any alarms are found, it will be listed in the bottom window. Please copy and paste that here also if it applies.

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 did some searching before I posted this problem but I couldn't find a solution that helps.

Everytime I try to install a program be it Itunes, the redistrubution package of the .Net framework, etc. I always get the error "xxxx.exe is not a valid win32 application."

I've read that a virus named Pretty Park could be responsible, yet it doesn't show up in my registry.

I'm utterly confused as to what to do.

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.

I have just downloaded 2 .ISO files from my university's website so that I can use a program at home. I also had to download a batch file to combine the two. This was performed with no problem.
The instructions on the uni website say to mount the combined ISO on a virtual drive, or burn it to media.
I have mounted it on a virtual drive, but when I try to run the program, I get the above error message.

The strange thing is is that I can see inside the 'disc', so can navigate all the way through. I know I'm running 64 bit, but the ISO provides both 32 and 64 bit versions of the software, and both produce the same message (except with the path of the .exe file added on to the E:\ drive. )
I would like to get this software up and running in the next couple of days, but my computer is not letting me!

Any pointers would be greatly appreciated,
Many thanks,

Answer:E:\ is not a valid WIN32 application

Are you able to copy the software directly from the virtual disc onto a folder on your local drive and run it from there?

What program is this? There may be related issues that I can delve into material for that may pertain to this.

Also, if you want, you can do a Procmon log of the error. Run Procmon, then attempt to run the program, then when the error message is displayed click the Capture (magnifying glass) button on Procmon and then save it as a file (select "All Events" option) and zip it up and send it over. Also notify me of the name of the .exe so I can identify it in the log (since they can get pretty large).

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.

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.

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.

Whether that fixes it or not, read the following and post anew in the Spyware section; to get cleaned out.

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.

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.

Hi All,

At the moment, I'm unable to open any applications including my usual anti-spyware tools such as Malwarebytes, Spyware Doctor, and SpyBot. When I try, a message would pop up to the effect of "[filename] is not a valid Win32 application." I've tried renaming the .exe file, but I would still get the same error message. I also did this in Safe Mode, but same results.

This all happened when I was browsing online (using Firefox) opening up a slew of sites on different tabs. I have been to all of these sites hundreds of times before and they are totally legit and trusted sites (film blogs, etc.). It took longer than usual for them to download and when they did Firefox closed and I was greeted by two fake anti-virus software pop-ups. I should've noted their names, but I immediately closed them and tried to run Malwarebytes. And as I said above, that didn't work. And that's where I am right now.

I googled my problem and this seems to be related to Bagle/Beagle? Is there anything to confirm this? If it is, what should my next steps be? Any guidance would be much appreciated.

My operation system is Windows XP.

Many thanks.

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.

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.
