Unless I'm mistaken, win32.py is part of pywin32 and Mercurial's
dependency to pywin32 was removed in Mercurial 1.8. So it's no more
needed but I can see that it is still part of the library.zip included
in the MSI installer (don't know why).
Maybe your pywin32 installation is broken. Does installing the latest
MSVC 2008 redistributable helps ?
