I don't have any insight into the python problems you're seeing but
I can explain why "setup.exe" asks you to upgrade to 2.6 when you're
at 2.7. 2.7 is, apparently, an experimental package. While "setup.exe"
allows you to install this, when it does dependency checking, experimental
versions are considered inferior to normal versions. So despite the fact
that the version number for python is greater in the experimental package,
you'll always be asked to upgrade to the normal released version. Like
it or not (and of course you love it ;-) ), this is expected behavior for
"setup.exe".
