    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:


    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!).
