How to activate Microsoft Office 2016 Professional Plus

Fresh installation: Go to office.com/setup, sign in with your Microsoft account or create one if you do not have one. Enter your 25-character product key without hyphens and follow the on-screen prompts. This links the license to your Microsoft account. Download the Office 2016 installer from your account and run it following the installation steps.

Already have Office installed: Open any Office application, go to File → Account → Activate Product, sign in with the Microsoft account used to redeem the key, and Office will activate automatically.

Upgrading from an older Office version: Install Office 2016 using the steps above. Your new key activates the 2016 version independently — your previous version can be uninstalled after confirming the new installation works correctly.

If you experience any issues during activation, contact our support team by email. We respond on the same day and will assist until your software is fully activated.
