[python-win32] How do I detect a 64 bit version of Windows?

[Mark Hammond]

You can check for "64 bit" in sys.version (or use the platform module as 
suggested by Brian) - if it is there it *must* be a 64bit Windows.  If 
it is not there (ie, it is a 32bit Python), then call 
win32process.IsWow64Process() - if it returns True it is a 64bit 
windows, otherwise 32bits.

This is basically the same advice as in
