It is usually recommended to install any prior version before a newer
version but if you have already an installation of Access 2003 on your
machine, I don't think that you will run into any real trouble. If you
install Access 2000 after A2003 and then that you have some trouble, then
mysuggestion would be of reinstalling Access 2003 - including all of its
services pack - after A2000.
Other will suggest that you take the precaution of removing A2003 before
installing A2000. This is probably the safest way.
If possible, make a full backup of your machine before attempting this
installation (ie, don't rely to much on the Restore functionality of WinXP
to revert back such a change if something goes wrong.)
