That's why I suggested bundling both 32bit and 64bit versions into the
64bit installer, or having the one installer know enough to do that for
you. But that idea got shot down. Until there are 64bit versions of
every app, we will continue to have this awkward behavior. I guess you
can blame MS if you want. There's no concept of a fat binary for
Windows, which is the approach Mac used to 64bit enable all their
applications and transition from Motorolla to Intel processors.

Unfortunately, there's a lot of software that would require hefty
modifications to work with 64bits--mostly in pointer arithmetic
routines.

Honestly, this would be more confusing. Even more so if it showed the
NOTE when the other version was already installed.
