Perhaps I wasn't clear:

The VS2008 installer as well as the most of VS tool chain appear
to be 32-bit binaries and thus writes its keys and values into
Software\Wow6432Node\Windows\.

If you then run a 64-bit Python binary, it won't find the keys
under the regular Software\Windows\ reg path.

BTW: This was a fresh Vista and VS2008 installation.
