Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Unfortunately, Microsoft’s direct download for the Office for Mac 2011 14.7.7 update appears to have been removed. Although the Description of the security update for Office for Mac 2011 14.7.7 article still lists the package, its download link now returns a 404 error.
Office for Mac 2011 is no longer supported, and version 14.7.7 was its final update. I could not find another working official Microsoft download for that update. I would avoid downloading it from third-party websites, as the file may have been modified or could contain malware.
If Office 2011 must be retained, the remaining safe option is to use an installer or update file that you previously downloaded or backed up. Otherwise, you would need to move to a currently supported version of Office or use Microsoft 365 on the web
Thank you for your understanding and time
