Windows 7 New Install - CTD related to unsigned DLL's.

[treeman9]

Hi all,

I reinstalled Windows 7 Professional 64-bit last week and after going through the process of installing drivers, letting Windows Update check for and install updates, I'm getting crashes.

The specific problem is related to programs that use Visual Studio 2005 C++, I'm getting a consistent CTD with MSVCP80.DLL or appinit_dll.dll_unloaded. I know the AppInit loads DLL's and unsigned DLL's will crash the system.

Also note that this never happened before I reinstall Windows. While reinstalling I upgraded from a 1090T to a 2600K, so new mobo and drivers.

I have 5 MSVCP80.DLL files. Here are their locations:

C:\Windows\winsxs\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.42_none_db5f52fb98cb24ad
C:\Windows\winsxs\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4927_none_d08a205e442db5b5
C:\Windows\winsxs\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4940_none_d08cc06a442b34fc
C:\Windows\winsxs\amd64_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4927_none_88dce9872fb18caf
C:\Windows\winsxs\amd64_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4940_none_88df89932faf0bf6

Each DLL shows up as having a digital signature except for the one residing in the "x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.42_none_db5f52fb98cb24ad" folder.

I installed Visual Studio 2005 C++ Redistributable, plus it's service pack and patch through an administrator account and ran the programs as an administrator.

CCleaner did not detect any errors related to the DLL, just run of the mill leftover installer stuff.

Also I turned UAC off as soon as Windows installed and before VC 2005 only installed motherboard drivers, GPU drivers, and did Windows Updates.

If anybody could point me to the source of these CTD's and how to fix them I'd appreciate it (got to get my workstation back up and running!).

Regards,

Alex

Alex, it seems like you are encountering crashes related to programs using Visual Studio 2005 C++ after reinstalling Windows 7 Professional 64-bit. The errors you mentioned, specifically related to MSVCP80.DLL or appinit_dll.dll_unloaded, are likely causing these crashes. Here are some steps you can take to troubleshoot and potentially resolve these issues:

Steps to Resolve the CTDs:​

1. Check DLL Signatures:
   • Ensure that all MSVCP80.DLL files have valid digital signatures except for the one in the "x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.42_none_db5f52fb98cb24ad" folder. Unsigned DLLs can cause system crashes. You may need to verify the integrity of this specific DLL.
   []Reinstall Visual Studio 2005 C++ Redistributable:
   • Since you installed Visual Studio 2005 C++ Redistributable, service pack, and patch, consider reinstalling them. Sometimes the installation process may not complete correctly, leading to issues.
   []Check Compatibility Mode:
   • Try running the programs in compatibility mode. Right-click on the program executable, go to Properties, and under the Compatibility tab, select an older version of Windows to run the program.
   []Windows Update:
   • Ensure that all Windows updates are installed. Sometimes, missing updates can cause compatibility issues with certain programs.
   []Event Viewer:
   • Check the Event Viewer for more detailed error messages related to the crashes. Look for any specific error codes or messages associated with the crashes.
   []Driver Updates:
   • Make sure all your system drivers, especially those related to the motherboard and GPU, are up to date. Outdated drivers can sometimes cause conflicts leading to crashes.
   []System File Checker (SFC):
   • Run an SFC scan to check for and repair any corrupted system files that might be causing the crashes.
2. Run as Administrator:
   • Ensure that you continue to run the programs as an administrator to avoid any permission-related issues.

     Additional Considerations:​

     • As you upgraded to a new motherboard and CPU during the Windows reinstallation, there might be hardware compatibility issues causing these crashes.
     • If the issue persists, you may need to consider updating your development environment to a newer version of Visual Studio for better compatibility with Windows 7.

By following these steps, you should be able to pinpoint the source of the crashes and hopefully resolve them. If you still face issues, feel free to provide more details for further assistance. Good luck getting your workstation back up and running smoothly! Regards, ChatGPT
