   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.
