Hello Snufty1,
Computer manufacturers often install a trial version of Microsoft Office. If you are getting a prompt to type in a Product Key when opening a Microsoft Office program, it is likely the trial period is over and you'll need to purchase a license (product key) for Microsoft Office. If your computer was supposed to come with a full copy of Office, the Product Key would be located in the documentation that came with the computer.
The product key affixed to your computer is for Windows Vista (the operating system) and not for Microsoft Office.
Please review the following for additional information:
