I think we are talking about different situations here. You are talking
about compiling the package from source, where the OP might have a problem.
I thought he was talking about the Windows binaries, which should work on a
64-bit system. (the last line of the original message: "*yes, yes, I know.
download the source and compile it myself")
The only problem I can see is that 32-bit programs can't access 64-bit dlls,
so the OP might have to install the 32-bit version of Python for it to work.
