I am getting this error when ever I try an open Outlook on one of our workstations.

The program is not registered properly. Please run Setup again. You don't have appropriate permission to perform this operation.

I could not find anything in Microsoft's Knowledgebase so I am wondering if any one here has run into this and what they did to repair it. I have unloaded and reloaded Office, removed the Outlook setup file and reloaded, and also tried deleting and then replacing the Mapi dll file. So far nothing has worked. This is a Win2000 system that was upgraded from Win98 and I am thinking that it might have something to do with that. I do have the user set up as an administrator.

Any ideas?
