How to install Microsoft Office for Mac 2016

Office 2016 for Mac is out of support and no longer receives security updates or bug fixes. A supported path is to reinstall the Office 2016 for Mac apps directly, then activate them with the license tied to that purchase.

Try this on the Mac:

1. Close all Office apps.
2. Open Finder > Applications.
3. Find Word, Excel, PowerPoint, and Outlook, then control-click each app and choose Move to Trash.
4. Download the full Office 2016 for Mac installer: Office 2016 for Mac Installer
5. Open the downloaded package and complete the installation.
6. Open an Office app and sign in with the account associated with the Office license.

If the installer downloads but Excel still does not launch or install:

1. Check Downloads for the installer package.
2. If the package will not open, move the .pkg file from Downloads to the Desktop and double-click it again.
3. If it still fails, delete the installer package, empty Trash, and download it again using Safari.
4. If macOS shows an unidentified developer warning, select OK, wait 10 seconds, move the file to the desktop, then Control-click the file and select Open.

If Office was previously installed from the Mac App Store, removing the existing apps and reinstalling from the direct Microsoft installer can resolve activation and app mismatch issues.

If Office 2016 is already installed but the old license is blocking activation, remove the existing Office 2016 for Mac license with the License Removal Tool, then open any Office app, sign in with the account for the new Office purchase, and run Help > Check for Updates.
