Yes I remember this when I was running Office 97.
Well are you thinking of installing a newer version of Office? If so then just install over the top of the original. The Add/Remove will remove the old one title and replace it with the new one.
If you not installing Office again then the only other long winded way is to Open Regedit and search for all the files in the office folder and delete them. There are a lot in the Win\Sys folder but you can leave those. Then I would suggest you download RegClean 4.1
of the web its made by Microsoft and its free. This will remove all the other references to office that you missed when searching Regedit.
