Your product key is different based on what version of Office you have. If the activation code or product key you have triggers a renewal window every time you open an Office application, you might need to update it or change it. Follow the steps in this guide to learn how.

  • With Office 2016, go to File > Account > Switch License and enter the new license or product key.
  • If an Office app isn't opening or giving you an activation or product code error message, use Command Prompt to change the active product key.
