Gotta strange thing going on here...

First of all, I'm having to rig a wierd software combo. Because of the nature of some of our files, I'm supposed to install both Access '97 and 2000 on certain computers (fun).

Well, all of a sudden, and though it had been working for a while, Access '97 won't work on one employees computer because all he gets is an error message stating there is no license for it. I uninstalled and reinstalled '97 twice, used to different installation CDs, and ran into the same error. No license (keep in mind I have to enter the CD key during installation for the sake of having a license!).

Any ideas?
