Big Sur 11.7.11 is outside the macOS versions supported by the current Microsoft 365 desktop apps, which explains why the latest release will not run on that installation. Microsoft supports the three most recent major macOS versions; an active subscription does not remove that operating system requirement.

 

First, check Software Update for an officially supported macOS upgrade for your Mac. If you can install a supported version, update macOS first, then open Word and choose Help > Check for Updates to update Office.

 

If this Mac cannot run a currently supported macOS version, there is no supported installer setting that makes the latest desktop apps compatible with Big Sur. Use Microsoft 365 on the web in a compatible browser, or install your subscription on another supported device. Keeping an old Office build also means missing security updates, so it is not a sustainable workaround.
