I once had a similar problem.  The problem was that I did not uninstall
the old python before installing the new one.  This would only be an issue
when python bumps to a "new directory".  I'm guessing there's a registry
issue somewhere.

I'm a little concerned about the privilige issue.  I'm no expert here.  I
suppose you shouldn't have been able to do the installation.  The fact
that you were able to seems to indicate that you have write priviliges to
c:\ . That would be odd.  Perhaps (???) you somehow have write priviliges
to c:\, but can't write to the registry ???

If you haven't wiped out 2.3, the best thing may be to go back to 2.3.  I
haven't upgraded yet.  (I'm waiting for a scipy installer for 2.4)

Next best: (IMHO) Try uninstalling all your pythons and then reinstalling
2.4.   You have some privilges, you may have enough to clean out the old
and bring in the new.
