To make it more specific, my configuration is 64bit Python on 64bit OS. 
Therefore it registers under:

The installer is 32bit, so my OS shows it
when it requests

The way to handle this would be either to get Python to register under 
both registry locations when installed on 64bit Windows (thus making 
itself visible to 32bit installers), or to make 64bit installers for the 
64bit platform (so the OS would not try to trick them and push the wrong 
key). None of those sounds terribly complicated.

Best regards,
