This is usually solved by letting the install complete. Use the Restore CDs supplied with the machine, but don't run the restore feature. Just let it fetch the files it wants from the CD.
For completeness and not saying you have a pirated copy of Office, there is an issue with some companies that loaded Office with the machine and set it to install on demand. The poor enduser is then not supplied the Install CD and is left with no where to turn since support for this is rarely found. Call the supplier if needs be to fixed.

Whenever I open Musicmatch Jukebox or at other random times when using my computer (Xp), an annoying installation process for MS Word 2000 starts up. It loads up and then says something like "insert CD 1 to continue" and I have to press cancel several times in succession to close it. MS Word is already installed on my computer(it came with purchase).
