No...registry entries are made to the HKEY_LOCAL_MACHINE which affect every
user.

You could however partition your hardrive and have two of the same OS's but
differing Office's...but that's unreasonable.
You could have two pc's in your work area, (networked of course) to run the
testing, and forsee the incompatablity.
You could run Remote Desktop Connection on your xp box, and connect to
another computer elsewhere in your network (other computer must have XP at
least).
You could research winvnc and use that instead of terminal services/Remote
Desktop.

But these are hardware answers, I'b be willing to bet that there's some
software you could buy, to test the compatablity.

If not, is it an option to make a new user profile and have this one
running Excel 2000?
