It’s free software. The author jokingly requests that users send him a picture of their hometown instead of payment. Must be funny in German.

Change Microsoft Office Key

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.

  • Click, Start – Run
  • 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.
