That makes sense.

That is correct - Biopython includes some C code (like NumPy).

We compile the Biopython Windows 32 bit Installers on a 32 bit Windows
XP machine. The compiler depends on which version of Python you want
to use. See the "Installing from source on Windows" section of this document:
http://biopython.org/DIST/docs/install/Installation.html
http://biopython.org/DIST/docs/install/Installation.pdf

You may be the first person to try this on 64 bit Windows. At least,
no-one has responded to my email to the dev list yesterday:
