Right - it sets the template summary to include Intel64, not x64. Furthermore only one architecture may be set in the template summary, so an installer may be only one of i386, x64, and Intel64 (although the latter are assumed to also be able to run i386 binaries). > What 32bit components should a 64bit build of Python include?

I was just making clear that I'm not familiar with what the MSI includes, and whether any of the components in a 64-bit install should be 32-bit or not. With the msilib code as is, it appears to be all or nothing, or rely on tweaking a global between calls to start_component. > 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)?

The former, with hints of caution: it appears the unused 64-bit code paths of msilib were created to best serve under incorrect assumptions. With what the code would create (with or without Win64 set), it will not generate the 64-bit registry keys that the 64-bit program will access. With Win64 set it will not even install except on an Itanium system. If you just want to get to the keys it currently sets, there should be an override parameter that causes the registry API to read the 32-bit keys even in a 64-bit process, but I'm not familiar with using _winreg. If there's interest and I can get pointers to where the MSI files are built, I can look into patching it. I don't have a convenient 64-bit Windows machine around to test any changes, though. -- Michael Urman _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
