Access 97 error No license on machine

Installed Access 97 from Office 97 prof disk on nt4 w/s. Then installed Office 2000 premium, which installed Access 2000. Our app requires access 97, so I uninstalled access 97 and office 2000. Reinstalled Access 97 and Office 2000 (without Access 2000)everything works fine except Access. When I try to launch I get exclamation box that says: Microsoft Access can't start because there is no license of it on this machine. Installs of both Access 97 and Office 2000 where complete and had no errors. What am I missing here.... Thanks
