[python-win32] WinSxS, manifests and binary distribution ?

I'm afraid some of the assembly stuff is truly black-magic to me, but 
I'll answer what I can.

How come what?  The C compiler generates this dependency based on what I 
have installed, which is VS2008 with no service packs.

I guess the manifest for that version indicates it supports the older 
version?

Is it possible that Windows is keeping an index of what is installed, so 
it *thinks* it will find the assembly in the SxS directory but fails to 
locate it and doesn't try the directory next to the modules?

Probably from something else you installed - pywin32 doesn't install it.

Please continue to share whatever you learn :)
