If you install Microsoft Office and find that the key is already in use, there is a quicker way to try another key instead of performing a full uninstall and reinstall of Office.

  • Type Regedit
  • Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\”version”\Registration
  • Click the plus (+) sign and you should find a couple of items that you need to delete: DigitalProductID and ProductID. One or both of these should contain a 32-character {GUID} (globally unique identifier).
  • Save and close the registry, reboot, and start MS Office again. It should ask you to enter another product ID and attempt registration.
