the SCons installer is created for 32bit machines, so you would have to 
install 32bit-Python instead. Would that be an option for you? For a 
more detailed discussion about the underlying problems you might want to 
have a loot at http://bugs.python.org/issue6792 .

For the VisualStudio toolchains, the "vcvars.bat" batch files get used 
to properly setup not only the paths to the programs, but a lot of other 
stuff. If you want to specify a target architecture (32bit vs. 64bit) or 
similar, please follow the instructions as given in the UserGuide, 
"Appendix A Construction Variables". Search for the keywords HOST_ARCH, 
TARGET_ARCH, MSVC_VERSION, MSSDK_VERSION...

Hope this helps you a little further.

Best regards,

Dirk
