    C:\Windows\SysWow64

    Thanks for the response Dave. I ran the program and thought I was lucky when I found the Adobe Flash updater linked to that. I unchecked it and thought just to be safe, I'd keep looking down the list only to find many, many more including many what looked
    like system files along with others. There are these that are checked also.

    _Wow64 File not found: C:\WINDOWS\SysWOW64\Wow64.dll

    _Wow64cpu File not found: C:\WINDOWS\SysWOW64\Wow64cpu.dll

    _Wow64win File not found: C:\WINDOWS\SysWOW64\Wow64win.dll

    _wowarmhw File not found: C:\WINDOWS\System32\wowarmhw.dll

    _wowarmhw File not found: C:\WINDOWS\SysWOW64\wowarmhw.dll

    There is one like this that looks valid- _Wow64cpu c:\windows\syswow64\wow64cpu.dll

    With all of the ones I found, I hesitate to disable them without knowing what I'm doing. If an entry says "file not found" and is active, would it be safe to disable those?

    Thanks

  4. C:/Windows/SysWOW64/D3DX9_40.dll missing

    MSVCR100.dll is missing on Windows 10

    If you upgraded your Windows from 8.1 to 10, it should exist a folder in C:\ named "Windows.old". Inside of it, it should exist two folders:

    • System32
    • SysWOW64

    I found MSVCP100.dll and MSVCR100.dll in them. Copying these DLL's to the respective folders made all the affected programs work again.
