Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
If the Amazon purchase included a valid Office 2016 product key and it has not been redeemed yet:
- Go to
https://office.com/setup. - Sign in with a Microsoft account, or create one.
- Enter the 25-character product key.
- Complete redemption to link Office to that Microsoft account.
- Then go to the Microsoft account dashboard at
https://account.microsoft.com. - On the Overview page, select Office apps, find the Office product, and select Install.
- Run the downloaded installer:
- Open file in Edge or Internet Explorer, Setup in Chrome, or Save File in Firefox.
- If prompted by User Account Control, select Yes.
- When "You're all set! Office is installed now" appears, select Close.
- Open Word or Excel to activate Office. In most cases, activation completes automatically after accepting the license terms.
If the key was already redeemed in the past, do not enter it again. Install from the same Microsoft account associated with the original redemption at https://account.microsoft.com/services or from the Microsoft account dashboard.
If Office does not appear in the account, it may be tied to a different Microsoft account.
If Amazon provided a third-party key and there are product key problems, use the seller’s instructions or support for that key.
Note: Office 2016 support has ended, and using it can expose the PC to security risks.
