· Q: 63: Change of the product key for Office 2003
The classical way is to uninstall the existing Office application and start a new installation with a new product key. The number can be changed more quickly in the registry.
In the registry editor, extract this subkey: HKEY_LOCAL_MACHINE \Software\Microsoft\Office\11.0\Registration
Delete values: DigitalProductID a ProductID
After having started MS Word or other MS Office 2003 application, you will be asked to enter the new product key.
