Office 2016 still installs and runs on Windows 11, but Microsoft ended support for it on October 14, 2025, so it no longer gets security updates. If you already own it, sign in at account.microsoft.com/services with the Microsoft account linked to your purchase and click Install next to Office 2016. If you have an unused product key, redeem it at setup.office.com first. For a supported option, consider Microsoft 365 or Office 2024.
Before you start
- Find your product key or linked account. Office 2016 bought as a one-time purchase is usually tied to a Microsoft account. Check the email or card from your purchase.
- Remove other Office versions if you have a newer version installed, since mixing versions can cause problems.
- Know the risks. Without security updates, opening files from unknown sources in Office 2016 is riskier.

Microsoft may no longer offer downloads for every older edition. If you can’t find your download, contact Microsoft Support with your proof of purchase.
