I ran into an interresting issue today for the first time, and after several hours of trying, I decided to take a look here. I've installed Office 2003 (propably for the 200th time) over Office 2000, and after installation encountered an error I've never seen before: Starting the applications from the start menu works, however every time I do that I see a "Microsoft Word is preparing to install ..." screen, which goes away after 2-3 seconds without asking for a CD or anything. I can use these applications just fine now.
However, when I double click on a .doc/.doc/.xls/whatever office document, I get an error telling me that no application has been configured for this document type, and that I should go into the control panel and do so. Looking there, I see that .doc files are set to open in "Microsoft Word", but the error still exists. Now when I login to the computer using the ADs administrator, the error is gone and I can work just fine.
The system is running Windows 2000 with SP4 and all the latest hotfixes. I've tried and installed SP1 and all hotfixes for Office 2003 as well, that didn't help. The computer is within a local Active Directory domain, the logged in user is a member of the administration group. Permission should not be an issue therefor, but I'd be glad to learn otherwise :)
Thanks for your help,
