Agreed - but unless I'm missing something, this release is not expected to
be a 32bit installer.

Why wouldn't it work for x64 machines?  Is it simply because msilib only
handles Intel64 when that flag is set?

What 32bit components should a 64bit build of Python include?  Perhaps you
mean *could* - but IIUC, there is no intention to release 32bit and 64bit
versions of Python in a single package (and further, IIUC, no intent on
supporting a 32bit and 64bit installation on the same machine, regardless of
packaging)

I'm afraid its not clear to me if you are agreeing with me (ie, that the
registry keys are incorrect), or disagreeing with me (the keys are what you
would expect a correct x64 install to create)?  I think you are agreeing,
but sounding a caution that it might not be trivial to fix, but I would like
to be sure...

Cheers,
