The ONLY thing that finally worked was to completely uninstall office 2007 and Reboot your pc.

Reinstall office 2007 and Reboot your pc.

Now you need to Update from the downloaded SP1 installer.

Those of you who have a disk, just bite the bullet and reinstall and prepare to recite numbers over the phone when you get dinged to reactivate your copy of office.

  1. No need to reinstall Office.
    From another source – found that any DVD will do so I updated my Office 2007 under Vista with a DVD of the Nutcracker Ballet in the drive!
    This was an infuriating error for those with Office preloaded as in my case, and hence had no Office DVD or CD to try,and don’t know why Microsoft does not cover this problem in their own help pages.

  2. Uninstalling and then re-installing Office was the only thing that worked for me! Previously I’d tried all the other suggestions thrown up by Google (such as having the disk in the drive when installing the update, disabling anti-virus etc), but this was the only thing that worked.

  3. The correct link to the microsoft article is without the dot at the end.

    Thanks for the help guys. Solved the problem for me.
