[python-win32] PyWin32 has stopped working/mfc90.dll error

[Lance Case]

I’ve installed the standard ‘pywin32-212’ app that comes with ESRI’s ArcGIS
10. Pythonwin.exe ran fine for me for a while, but I’ve somehow managed to
break it. I’m getting “PyWin32 has stopped working”. When I check the Event
Application log, the error says “Faulting module path: C:\Windows\WinSxS\
x86_microsoft.vc90.mfc_1fc8b3b9a1e18e3b_9.0.21022.8_none_b81d038aaf540e86\mfc90.dll”.

I’ve confirmed that the file is there, but it won’t allow me to replace it.
I then noticed that C:\Python26\ArcGIS10.0\Lib\site-packages\pythonwin
contains the same DLL and that there is a ‘manifest’ file.

Does anyone have any suggestions for fixing this error? I’ve tried
reinstalling Pywin32 a few times with the same results.
