After that, download and install the most recent version of Microsoft AutoUpdate via this official link: Download Microsoft AutoUpdate for Mac.

Additionally, verify that you have sufficient disk space and a reliable internet connection, and consider running the installer from your desktop rather than from cloud storage services like Dropbox or Google Drive.
