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

I believe I switched the entire Windows installation at least once in
this time (from XP to Windows 7), so it's unlikely related to my
personal installation.

Please do. It would also good if somebody volunteered to reproduce
the issue.

Please don't. Or, at least, make it more specific. If you have manually
corrupted your Python installation (by deleting essential files), you
have to accept that the system installation procedures will fail.

It might be possible to recover from the loss of a specific such file;
for that, we would have to identify what the file is. However, the
standard procedure should be to repair the installation before
attempting an upgrade.
