The MSI installer is generated using msilib.py from http://svn.python.org/projects/python/branches/release27-maint/Tools/msi that is dependent from external win32com module. We also have internal 'msilib' module that is unused for some reason.

Is it possible to incrementally transition from Tools/msilib.py to builtin 'msilib'?

See http://codereview.appspot.com/4080047/ for the start of the thread.

If this report is (still) true I'd assume that we'd want to eventually action it. Otherwise can we close this as out of date?

[loewis]

There is a high chance that 3.5 might use an entirely different MSI generator, possibly based on WiX. If that happens, this issue will be outdated.

This can now be closed as out of date.
