Or just a Vista bug.
A possible option could be using wine64
(http://wiki.winehq.org/Wine64) . But is probably more work and if
even if it did work it may not be informative.

I virtually avoid windows for work so I can not answer your question.
I knew about the issues from another person trying to compile code
using WinGW on another almost identical 64 bit Vista system. Even the
related thread seemed to solutions that only worked for some people
and I do not know if a solution was found in that case.
Anyhow, I do agree that having Python 2.6 support is more important
than running the anti-virus software.
