Driver Digital Signature error when using signed drivers (Code 52)

Question: Driver Digital Signature error when using signed drivers (Code 52)

Hi,

This is my first post on these forums, so please excuse me if anything is wrong.

Details of the problem: I have a Sony VAIO laptop that runs Windows 7 Home Premium x64. I recently downloaded the same version from digital river that has SP1 included and installed it on my laptop. I installed the drivers that I had downloaded from sony's esupport site which went fine. After I rebooted and tried to install the rest of the drivers, I started getting the Code 52 error: Windows cannot verify the signature of this driver. I've seen that every driver can be installed immediately after the system has been booted the first time (after a clean install). Once rebooted, it starts giving the code 52 error. I can't install my iPhone drivers (through iTunes) or PS3 utilities because of this. I'm wondering what changes during the first reboot. I must also say that these very same drivers were used on the previous build of Win 7 HP that I was using except that it did not have SP1 integrated.

Has anyone had a similar experience? I know that the digital signature check can be disabled using bcdedit.exe but I want Windows 7 to work the way it should: it should stop me from using unsigned drivers while installing signed drivers correctly. Does any one have any clue to what's going on with my Win7 on my laptop?

Answer: Driver Digital Signature error when using signed drivers (Code 52)

Hi ajayav, Welcome to Sevenforums.

Boot into Advanced Boot Options and disable driver signing checking.

The Advanced Boot Options screen lets you start Windows in advanced troubleshooting modes. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.

Disabling driver signature enforcement has helped a lot of users in fixing the issue.

You may also delete the USB "Upper Filter" & "Lower Filter" Entry and check if that helps.

Before we go any further, please first backup the Registry.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

1. Click “Start”, type “regedit” (without quotation marks) in the “Search” bar and press Enter.

Note: If UAC (User Account Control) pops up, please accept it.

2. Right click “Computer” (the root node) in the left pane, click “Export” under the “File” menu, choose “All” under “Export range”, and select “Desktop” in the “Save” in box and type backup in “File Name”. Click “Save”.

Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file.

3. Click “Start”, type “regedit” (without quotation marks) in the “Search” bar and press Enter again.
4. Locate the “UpperFilters” value under the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}

5. On the “Edit” menu, click “Delete”, and then click “OK”.
6. Locate the “LowerFilters” value under the same key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}

7. On the “Edit” menu, click “Delete”, and then click “OK”.
8. Quit Registry Editor and restart the computer.

I scanned my computer with AVG (Which just recently has been acting funny), and I found and deleted a bunch of tracking cookies, but there were a hand full of files that I don't think were infected, but it said next to them that "The file is signed with a broken digital signature" Does anyone know what that means, and how to fix it?
Thanks! O h and most of those files were from C:\WINDOWS\Installer

Answer:What does it mean if a file is signed with a broken digital signature?

Per AVG this is for information only
The file is signed with a broken digital signature
The reported file was signed with a digital certificate ensuring its integrity. However due to changes to it, the certificate no longer corresponds with the content. This might happen when file is infected but also when it was incorrectly updated, broken due to some error or when the digital signature expired.

My AVG antivirus has detected a a file with a signed broken digital signature, issues by : DT Soft Ltd.
C:\Users|Denise|Desktop<Recovered programs and music<Downloads<DTLite4454-0315.exe (sorry somehow I have managed to activate the red keyboard items and don`t know how to inactivate them and get back to the normal keyboard items!)

Anyway, with this broken digital signature, I cannot get on to the internet and access my e-mail or open a file or anything. AVG does not have an option available to `remove selected`or `remove all` hence using laptop to send this message. Can`t even download the TSG SysInfo either to give you more details I`m afraid.

My main frame was recently upgraded to windows 7. I therefore have NOT been able to do the essentials like Hijack this, etc. before posting this message as am unable to use the keypad and get anywhere. Can`t type a single word, letters are repeated or missed and one cannot go back and try an insert or rewrite etc. In fact at this present moment in time, I cannot even get a single letter to appear when I use the keyboard!

Is there a way of getting rid of this with AVG or disabling it without having to type anything using the keyboard) so I am able to open the internet to connect to the forum and try and sort this out on said computerÉ

I am presently on the forum getting assistance from Jeff with my laptop,Windows Vista, for malware issues as well.
 

Answer:signed broken digital signature, keyboard totally inactive

Can I just delete this file from it`s location in the C drive as I cannot find it on my desktop for uninstalling or will it have attached to other programmes and filesÉ (question mark)!

Hi All, I've been struggling for about a month.  Since I reinstalled Windows 10 Home (1067) (on a new SSD) the 100-15IBY Camera and High Definition Audio Driver has failed with Code 52 unable to verify digital signature. Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52) I've tried everything... permissions on files, bcedit command lines, downloading newer drivers from Realtek, reinstalling windows again with Legacy and then UEFI modes... disabling Secure Boot, reinstalling again with Secure Boot in "Setup - Disabled" mode... The only way to get the audio and camera to operate is to reboot in safe mode and disable the Driver Signature Enforcement - that only works for a single boot.  So I know the drivers are correct and the devices work... it's a trust issue with the drivers. The High Definition Audio one is specifically a Microsoft Driver... why wouldn't that be trusted!? Please anyone?  It must be a common problem - has anyone solved it? Tony

I ran rkill to check of problems with my system XP/SP3. The file mqac.sys does no have a valid digital signature. I have 6 copies of this file on my system from past sp's. how do  determine which one to use as a replacement? How do I check to see if it is signed, and if it is do I just swap them out?
 
Have already cleaned system, getting rid of old files, cleaning the registry, I.e. a deep cleaning to speed up my system and clear up problems. I have no malware or virus' that Avast and several other scan tools and detect.

Answer:no digital signature on mqac.sys in %windows%\system32\drivers

from what I can gather, mqac.sys is part of the message queing system (MSMQ) that is not part of a standard XP install, but is a free add-on (at least for XP Pro) if you wanted to install it. It might be part of something called 'Snap Desktop' (which I also don't have)
 
http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/snap_desktop_msmq.mspx?mfr=true
 
Does this sound like something that you would have installed on your machine?
 
If so, I doubt that it's malware, even though there are multiple copies without signatures. I'm pretty sure I have a few Windows system files that aren't signed.
 
Unless you think they are harmful, I would just leave them be- don't fix what ain't broke.

Yes, you can use this in vista/7, if your needing to test it with a certain amount of drivers you are installing this will help.
Windows 7 Simplified: Sigverif.exe
If your needing this for windows xp, not quite sure but you could check with a windows dedicated forum and they'll let you know immediately if it is or not.

Good day everyone!

I recently noticed that my graphics for Fallout 3 are quite choppy and particle effects are pixelated, so I went and checked for new drivers for my ATI radeon 5570. I downloaded the auto detect driver utility on AMD's website and downloaded the appropriate package for my Windows. I follow their installation guide to upgrade from older drivers and launch the "Express install" option.

My problems starts here, I get a 50/50 chance that, while installing the display driver, the screen goes black and flash a couple of times followed by a BSOD (I don't have the details it disappear too fast ). The other half is that the drivers will go past the screen going black and flashing, but the display is set to 800 x 600 (the basic resolution). I restart the computer only to find that I cannot ajust the display past 1024 x 768 on my 1920 x 1080 supporting monitor. Going inside the driver manager -> displays, reveal that my 5570 is not working (the exclamation mark icon is visible) and that "windows cannot verify digital signature[...] Error code 52"

I've searched all over the internet for people with a similar problem but found nothing to help me. If anything, I've found that other windows machine with seven are able to install this particular driver without a code 52. For now i've rolled back to the old settings that worked before.

Can anyone assist? I'm running out of ideas.

Cheers!

Hello, I'm new to this forum. Excuse me if this was posted before. I recently upgraded from Vista x32 to 7 x64. I'm getting the error stating, windows can't verify the digital signature for this file, winload.exe. status 0xc0000428. The computer will not boot unless I have the windows disk in the cd drive. THen, everything is ok. I tried just about everything that I found but, the same old thing. My question is, why does it boot to windows with the disk installed whereas the disk has the same files that were installed on my hard drive? I never had this issue with Vista. I even re installed win7 to see if that made a difference but it didn't. I tried bcdedit, bootrec, sfc /scannow, disable integrity checks, starting in safe mode, etc. If I keep the windows disk out, when booting, and after getting the error screen, it asks if I want to boot to Vista, which I don't even have. I deleted the windows.old folder. I have all the updates installed. Could this be a bug in windows 7 or is there something I'm missing. I'm willing to try anything. Thanks

I uninstalled an HP scanner from my media center running Windows XP. I went through and deleted everything I could find that had to do with the scanner. Now I still get a pop up message box upon initial boot that says "No Digital Signature" and the title on the box is HP Precision Scan LT Setup. The program is deleted and I can find nothing when I search. I can close the box but it reappears within a short time. Any help would be appreciated.

Since it wasn't uninstalled correctly you might try going into the registry & delete all instances of the HP scanner. Run regedit & search for whatever reference your getting in your message & delete the keys.

I have a Lenovo ThinkPad T440 (20B6005RUS) running Windows 7 Pro 64 bit with service pack 1. The audio drivers stopped working. Device Manager has 2 sound devices, High Definition Audio Device and Realtek High Definition Audio.  To get the drivers/sound to work I have to press F8 and disable the driver signature enforcement. I went on Realtek's website and tried their drivers. They did not work. I was told a Windows update caused the audio driver to stop working. I uninstalled both devices with their drivers and hoped Microsoft's own audio driver would install but a driver is not found. Is there any solution I can try? Should I try a different audio driver? I appreciate anyone's help. Attached is a screenshot of what I get in Device Manager.

Hey there,

I have an M11x laptop and I've frustratingly been trying to figure out how to turn off Window 7 Home Edition's digital driver signature check when I try installing drivers for my new Numark Virtual Vinyl product. It says it can't install because it doesn't recognize the signature. I went online to do some research and apparently Numark has released the 64 bit drivers (I have 64 bit Windows 7) as a beta version; however, I've seen other people on forums have success with installing the drivers to their 64 bit by holding down F8 when they restart their Windows 7, which will bring up a boot options to where you can turn off this feature.

When I try holding down F8 on mine, it just BEEPS really loud at me and won't bring up an menu and then just goes through it's regular startup. I do have an F12 option which will bring up boot options but there's no option via that method to turn off the digital signature check. After this didn't work, I also tried another method I read about via google where you could disable the check by putting in a code in the cmd window putting your computer into 'safe mode', which I tried as well and still had no success with this method either!

Are there any tech wizards out there who would know how to disable Windows from doing a driver sig check on these particular drivers? (Numark Virtual Vinyl 64 bit drivers)

PLease please if so, drop me a line! I really want to use my product!

Hello!

Following a guide in another forum, I was able in the past to install Windows 8 in an old Pentium 4 system without NX/PAE support. I'm not going to go into details here, but the process involved extracting the installation files from install.wim to a hard disk and patch certain files to bypass compliance check. One of them is ntoskrnl.exe. I was wondering if this is possible with Windows 10. So I followed the guide and managed to install Windows 10 to a VMWare virtual machine (I didn't have a real machine available). Yes, Windows 10 work, so at least in theory it should also work on a real machine. The problem is that in every startup I get a BSOD that ntoskrln.exe digital dignature cannot be verified or similar. I already tried to enable test mode and ignore signatures, as well as disable Windows Defender, but the problem persists! In order to load Windows I have each time to press F8 to get into advanced startup options and then select 7 to ignore driver signing. How can I disable system file check at startup so I don't get this message? Any ideas? Before you rush to say "why bother", I answer "for the challenge, because I can".

I need some help with a Windows 7 (x64) system where bluetooth and usb devices have suddenly stopped working. When I go into device manager I see that my Intel USB 3.0 extensible host controller and my Intel Wireless Bluetooth show exclamations
on them. They both report that "Windows cannot verify the digital signature for the drivers required for this device".  

This machine has been working fine for a while but suddenly stopped working correctly earlier this week.  So far I have uninstalled recently installed MS patches. I installed the most current version of the drivers from Intel for these devices.
I've also ran sigcheck against both drivers and confirmed that they are signed. 

As a work around, I use F8 and boot with driver signing verification turned off but that is certainly not ideal as I have to remember to do so every time the computer is restarted. Anyone have suggestions for a permanent fix?

I have my name written by my own fair hand saved as a macro for word documents and thought it would be nice to have it as my signature in outlook express but cannot work out how to insert it (xcuse the terminology there..) I have Windows 2000 Pro. Word 2000 and OE 6. Is it possible?

Answer:How to insert signed name as OE signature

The only way I know, though there will be simpler way that I don't know, is1/scan in the signature and save the image as bmp., jpeg etc2/ open the image in Word and save as an HTML document.3/Open OEOn the Tools menu, click Options, and then click the Signatures tab. To create a signature, click New and then either enter text in the Edit Signature box or click File, and then find the text or HTML file you'd like to use. (The one you have just saved)Select the Add signatures to all outgoing messages check box.

I've installed Win 7 on my Laptop. But when I launch (without booting from Bootable USB), it gives me an error:
File: \Windows\system32\winload.exe
Status: 0xc0000428
Info: Windows cannot verify the digital signature for this file.

The problem is when I boot from my Bootable USB it acts normal. Like nothing is wrong. It's just normal Windows 7 like I'm used to.

I searched on other topics but it seems that everyone issue is fixed by using the bootrec using the bootable DVD. Although I can't access that since I'm using an USB AND when I boot using my USB it's acting normal.

I just upgraded my Sattelite L300 with the Toshiba Vista Home premium DVD"s (Dutch version).

Step1: Toshiba Upgrade DVD deleted all drivers as promised
Step2: Windows 7 Home premium Upgrade DVD installed without problems.

Step3: Toshiba upgrade DVD refuses to start witj following error (translated from Dutch):
Can't control the digital signature for this file.
A recent change in software or hardware has probably installed a file with a wrong or damaged digital signature...

Apart from some basic Windows programs (IE) I can't run, install, nor delete any other program anymore - always this error...
Other utilities (wifi for instance) just give the message that they have encountered an unknown error...

I tried to upgrade some drivers from the Toshiba website but not a singe downloaded file will execute... (all with the same digital signature error)

What now?

Edit:

I managed, I think, to install the Toshiba drivers in safe mode, but several programs still fail to run, install or even delete ...
all giving the signature error... (ccleaner, revo uninstaller, also all setup files downloaded after the 7 install)

Touchpad will freeze now and so often, leaving only Ctrl-Alt-Del to restart the computer

I found a solution to disable the digital signature check in Windows 7, but for that you need to open CMD as an administrator.
Guess what, even CMD refuses to open because it doesn't recognise the digital signature..

How do I switch this thing off before I throw my PC in the dustbin...

I am completely stumped by this problem. I will do my best to explain it and see what you fine folks can do.

I had an older bluetooth dongle, off-brand model, 2010-2011 year, that I installed on my new desktop computer. It worked, but sound quality on my Sony Dr-BT101 headset wasn't great. It worked well with my bluetooth-enabled phones and tablets, so I suspected the dongle. I bought a CSR8510 dongle, which came with a CSR Cambridge Radio Harmony software stack. I installed the software, and turned on the headset, paired it, but no sound came out of the headset. I went to Sound, saw no entries. Went to device managers and saw the parts in yellow. I tried to update the driver but all I got was Code 18 error and this weird message in the picture. I clicked on properties and saw this message.





Quote:
The drivers for this device are not installed. (Code 28)

There is no driver selected for the device information set or element.




I am stumped. I've tried uninstalling, re-installing, installing other Bluetooth drivers, waving a magic wand, none of it has worked. I'm thinking it's a problem with the Registry, but I am not sure how to proceed.

Any ideas?

Greetings,

A few days ago someone has e-mailed me and their e-mail in my inbox appeared with a red ribbon next to it. When I open it or preview it, I can read what they wrote and see that they also have a signature.asc attachment.

Our e-mail environment is an in-house hosted Microsoft Exchange setup. With instructions from Microsoft at https://office.microsoft.com/en-us/...ges-with-a-digital-signature-HP001230539.aspx I created a digital signature using Comodo. When I send a signed message, Outlook converts the message I wrote into an attachment, attaches it to a new e-mail with a blank body but with the Subject I wrote, and sends it to intended recipients.

How can I get it to sign messages without converting the whole e-mail message into an attachment and forcing recipients to open the attachment to read my message?

I want to know how, with Outlook 2010/2013 on Exchange, I can send messages that too have a signature.asc and receive the ribbon mark.

While downloading the latest version of my ISP's software yesterday, the installer stopped the installation after the download and declared that it was unable to verify the integrity of the file (17.4MB) that it had just downloaded.

Looking at the properties of the file, indeed, its cetificate stated its Digital Signature Invalid.

Viewing the certificate details, a Copy to File button exists which when pressed invokes a Certificate Manager Export Wizard.

My understanding of "Digital Signature Invalid" is minimal at best, but I suspect that the download file was changed after it had been signed which would explain the problem.

I run a Win98.SE platform with 512MB RAM and 40GB disk - so, system resources are plentiful.

Does the ISP need to re-sign the download file to correct the problem?

Does my platform need a new Root Cerrtificate for the ISP installed to correct the problem?

Or, do I need to export the "invalid digital certificate" via the Certificate Manager Export Wizard to proceed with the installation?

I have already contacted the ISP with these details, and since they are already sending me a second CD-ROM of their new software, they claim that should fix the problem.

While I am willing to wait to see if that corrects the problem, I would like to know your thoughts about the digital signature problem and its correction that I have explained to the best of my knowledge above.

Thanks in Advance,

-- Tom

hello

downloaded 2 programs from cnet [never had a problem here] and got warnings on both about publisher being unknown because digital signature was invalid.
couldn't find cnet's knowledge base and so I don't know what my next step should be.

also,THIS site doesn't seem to have much on the issue. any advice would be appreciated.I thought this was a common problem that would be easy to investigate.

I posted once before months ago, but didn't get any replies.

We have to use PKI/digital sigs for one of our main clients. We send attachments and emails encrypted because they include patient name, partial social security numbers and health information about the patient.

My PKI works fine, I have been having employees get them and they work fine. My boss has trouble with his. I can send and receive from him. He is using Outlook 2003. When he gets a certificate from a client and adds it to his outlook contacts, it shows up as being his certificate and not their certificate.

We have worked and worked on this and can't figure it out. We are in seperate offices, but I am going to try to get to his office this weekend to see if I can figure it out. We got the certificates from Versign and they don't provide any support. We have read all the help pages, emailed and not gotten any help back from them.

Any ideas on what could be wrong. I am running out of things to check.

Thanks.

Nancy

I Think my computer is infected ( I have Windows XP) because it has gotten really slow and isn't doing what it should, so I recently subscribed to McAfee antivirus. After paying for it I had to download it but every time I try, a security warning pops up and tells me "This file was blocked because it does not have a valid digital signature that verifies it's publisher." I have gotten that same warning every time I try and download new programs and It's preventing anything from downloading. I'm not sure what to do because I need this Antivirus. It started doing this about a month ago but before that everything would download properly. Any help with this would be greatly appreciated, Thanks!

Hello!
Can you tell me what is "Programs digital signature"? According to my knowledge some security software categorize programs trustworthiness using program digital signature.
How do program developer get digital signature?
Why some programs not have digital signature?

Answer:What is Program Digital Signature?

To #1 I'll clip you what Microsoft has to say about that:





Quote:
A digital signature is an electronic security mark that can be added to files. It allows you to verify the publisher of a file and helps verify that the file has not changed since it was digitally signed.
If the file doesn't have a valid digital signature, there's no way for you to be sure that the file is actually from the source it claims to be from, or that it has not been tampered with (possibly by a virus) since it was published. It's safer to avoid opening the file unless you know for certain who created it and whether the contents are safe to open.
Even a valid digital signature doesn't verify that the contents of the file are harmless. You must decide if you should trust the contents of the file based on the identity of the publisher and where you are downloading the file from.


What cracks me up about that statement: They basically say "Even if we digitally sign the file, you can't be sure if it's authentic" Doesn't that statement contradict the sense and purpose of the whole process ???

As for #2 as a dev you can submit your file to Microsoft to obtain said digital sign

As for #3 because it costs money and it takes time for your files to be processed. Sometimes the cost of the driver or program doesn't cover the licensing fees ...that together with Microsoft's statement, that even a signed file could be bogus might influence decisions not ha... Read more

Two web questions for you ladies and gents out there.

1. I want to include a couple of pdf files that open in the browser using the acrobat plug-in. Anyone know if this was broken in IE 6 I heard that they messed up a lot of plugins and wondered what the best way to do this is in html so that I include the largest majority of users out there.
2. I am creating a web-based form that used to be a pdf that applicants printed off and mailed in. Problem is they used to sign the application and mail it in. I know that there are digital signatures, but anyone that has tips and experience with something like this I'd love to hear how you managed to overcome this problem. Did you use digital signature technology or go with an alternative method?

Thanks for the help.
 

Answer:pdf in window and digital signature

Hi.

AFAIK the plugin for the pdf is still buggy in IE6.0. I'd be interested to hear otherwise. I've advise my clients NOT to update at this time.

As for the digital signatures.....I have one called on-sign that I use in conjunction with my PDA. However, to use it with Acrobat I need to do some fancy cut & paste from another app.

The problem with digital signatures is I'm not sure how they stand-up in court. For legal type stuff I still use the old pen & ink method. But for correspondence I don't have any problem plugging in my digital. I think you will have to check the laws in your area about such things.

Hello,
I have signed up to broadband via BTinternet and I have to download their security stuff. However when I try to run this programme a window pops up saying- Internet explorer security warning, windows has found a problem with this file- Name (blank)- Publisher unknown publisher- file was blocked does not have a valid digital signature.
The only option is to click the ok button and that is it, no option to over ride. I then noticed that this happens with every file that I download including trying to upgrade graphics drivers from Nvidia site which is pretty annoying as they are out of date. So far under advice from Bt and the computer manufacturer I have wound back windows, turned off every security setting, run as administrator, removed the antivirus software and even done a complete vista re install. I cannot believe that this is a unique problem but the previous mentioned tech support teams are baffled. Please help

I upgraded a desktop and laptop from Vista Ultimate to Win 7 RC and have the same problem on both. I can't install programs, run msconfig, cmd, regedit, etc, because I receive a digital signature error that is supposedly related to a recent hardware or software change. I can't even edit the properties of the accounts because of this same error.

Interestingly enough on my laptop one account shows a blank programs list when you go to start-all programs, but on the other account they show up. I restored the desktop from my windows home server and will shortly do the same on the laptop if I can't figure out this problem.

Any ideas?

Hello Awraynor,

It may be a issue from the upgrade. You might see if doing a clean install of Windows 7 may work better for you instead.

Do you have to have the digital signature of your recipient to be able to successfully send them an encrypted message? Or, do you have to have that recipient saved in your 'contacts' list?

I have read the section on encryption and digital signatures in the 'Step by Step' book and it doesn't mention either of these needs. But, I have had several people tell me that I need both in order for them to open an encrypted message. I'm so confused now that I'm ready to go back to snail mail and interoffice envelopes!

I hope someone can help me - or refer me somewhere for the problem I'm having this weekend. My problem is w/QuickBooks Pro 2006 version. QB Technical support isn't available until Monday morning, and I need help now.

I have a Compaq Presario 6350 computer, XP sp2, I use AVG and Ad-Aware. I have lots of memory and I'm still on dial up.

Here's my story: I was having problems w/other issues on my computer a few days ago. A friend of mine determined I needed to do a reinstall and data restore. He did back everything up to disk.

I thought everything was working perfectly and he'd really helped me out, BUT - when I tried to do payroll in QB, a message popped up saying I had to do payroll update first. It appeared to be working fine, but it was taking forever, so I knew something was wrong. Then, I got the dreaded message -- Error 15222. "The payroll update did not complete successfully. QuickBooks could not verify the digital signature within the update file."

I called my friend and he told me to insert the Backup of "important data" and look for the file I need. However, I have no idea which file I need. I did go to QB support website and followed the instructions as listed. I went to "add & remove" and followed the prompts and did a repair through there. The message stated my repair was successful. I did a reboot and thought I would be able to successfully update my payroll. But - still no luck.

Accessed: Thursday, September 12, .... (same date/time created)
AND under Security, the following had read and execute privileges: SYSTEM, TrustedInstaller, Administrators, Users (I was mainly concerned with the Users one.) I'm pretty sure the TrustedInstaller (I'm assuming Microsoft) had ownership privileges before

Answer:conhost.exe digital signature

Hi,
 
Based on my knowledge, conhost.exe is the new host process for console windows. Previously those were handled by csrss.exe which is the ?Client Server Runtime Process?, a process running with system-level privileges. The conhost.exe process sitting in
the middle between CSRSS and cmd.exe allows Windows 7 to fix both of the problems in previous versions of Windows?not only do the scrollbars draw correctly, but you can actually drag and drop a file from Explorer straight into the command prompt.
 
I would suggest you to see the following link for more information.

I had some problems with my video care, an ATI All In Wonder Radeon, so ATI told me to do a few things, which now has screwed up my display drivers. I have tried to re-install the video card, but I get the Digital Signature Notification error. It says that the driver may not have been tested by Microsoft, and wont be installed. I have tried to change the settings to warn, but it wont let me click the advanced tab, it has been greyed out. I have tried to download the drivers from the ATI web site, but they wont install properly. Is there any way to change the warn vs block settings in Windows ME?? thanks in advance kirk
 

Answer:Digital signature problems

Just a though

Are you logged on with username and password rather than guest or default.

Have you tried windows updated, it may offer you a video driver to temporarily correct the problem

Had trouble like that along time ago, ended up using windows update at first, finally got the advanced to warn rather than block.

Hi Guys

Have tried this post on " am I infected" forum without reply. Probably wrong forum anyway. I have Vista OS with AVG 2011 free. When I scan it comes up with 7 files with the narrative " this file has a broken digital signature issued by the Microsoft corporation" I have no idea what that means, can anyone enlighten me?

regards
Cluey

Answer:Broken digital signature

Although I'm not familiar with this particular AVG 2011 message, the meaning is quite obvious to me.

AVG 2011 has checked the digital signature (Authenticode) of Microsoft executables, and found 7 executables produced and signed by Microsoft, that have an invalid signature.
The most common reason for an invalid signature is that the executable has been modified after it was signed.

Does AVG tell you which executables have a "broken digital signature"? Can you share this with us?
Because one possible explanation for a modified executable, is that you have a malware infection.

In this blogpost, I explain how to check digital signatures: http://blog.didierstevens.com/2008/01/11/the-case-of-the-missing-digital-signatures-tab/
