Fixing this required manually cleaning up leftover CPython 3.4.0rc3 windows installer registry entries. Note that the issue could not be fixed by using the CPython 3.4.0rc3 installer as it failed due to the same problem.

Did you try the 3.4.0rc3 "repair" installation? That should have undeleted (repaired) the files that you had manually deleted.

Just tested this out and repairing the same matching installation does revert the removed files. It does not reinstall pip and setuptools packages but that can be done easily by hand and so can be filed as a minor enhancement issue for the future.

That at least provides a way to remove the the original installation in some way without having to manually remove its related Windows Installer registry entries.

The problem with the 'Add/Remove Programs' dialog still makes this issue a bit complicated because a user not well versed in how Windows Installer tracks its installations internally would not see the installation in the 'standard place' where he is supposed to look for it, and would just be told by the new installation that 'something failed'. To use a 'repair' installation he would need to 'guess' which installation he used before and run its installer directly.

When the 'Add/Remove Programs' dialog is fixed, user will be able to see & repair the installation from there, and even remove it directly if the uninstallation fails (I recall Windows asking if you want this if it can not uninstall something).

I'll try to open an issue for the 'Add/Remove Programs' dialog issue soon, and I'll add a comment about the 'repair' situation there as well.
