Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello
Is this on MacOS?
What MacOS version do you have?
If you have MacOS 14 or above,
First, see if you can update your Office apps. Open Word for example, click on the 'Help' tab >Check for Updates. Make sure you choose Update All when prompted. Let the process run through, can take a bit time. See if that works.
Otherwise, use the Update method in this article: https://support.microsoft.com/support/known-issues/unknown-error-0x0-license-not-found-error-microsoft365-macos
If it still doesn't work, please uninstall the apps. Follow the instructions here for complete uninstall.
Then reinstall this way:
If you signed up via Apple App Store, then download and install from the App Store.
If you signed up via Microsoft directly, please go to https://www.office.com
Sign into the Microsoft account you used for the subscription. Click on the 9-dot icon on the upper left > More apps.
Then on the upper right, click on "Install apps". This will now download the installer file. Once downloaded, click on the file to install. It will install the Desktop version of the apps for you then.
However, if you have MacOS lower than 14, please let me know what it is, because the instruction is not the same.
