I built an MSI for Python 3.3 on Windows 7 and installed from it - the resulting installation seems to work OK in that it passes all tests except test_tcl (intermittent failure). However, when I uninstall, python33.dll is left behind in System32. If I rebuild Python and the MSI after some changes and reinstall, the old python33.dll is not overwritten with the new one.

I guess this is a misconfiguration for your system. This DLL is reference-counted, and you must have arranged the reference count to be >1 somehow. Inspect the MSI log for details.

Yes, the refcount was 1 after uninstallation - possibly it's been like that for a long time. I'll close the issue, but one thing occurs to me - isn't the DLL's version resource updated when you rebuild? Why wouldn't the newer version in an MSI being installed overwrite the older one in Windows\System32?

The version number is not changed on every rebuild, only when patchlevel.h changes.
