I have two PC that we want to switch software on. One has MS office97 on it. We want to load MS Office97 Pro. We first removed office97 from the PC. We then installed office97 Pro. When we try to open Access it gives us a message “this machine does not have a licence for access”. We know it is a registry problem? We have tried several times and it will not work? The other parts of office work fine. What are we doing wrong? The other PC where we loaded office97 over office 97 Pro works fine?
