You do not have permission to open the application "Microsoft Update Assistant.app". Error

Just wondering if anyone has filed a case with Microsoft in regards to the error messages below.  We noticed this happening when trying to push the last 2 versions of office365.  Hoping to get a case# so that we can refer to it.

Yes. I saw that back in August when I had a policy to install Office 2019 and or the individual VL apps. What many have found to be effective is including the Microsoft Autoupdater as a separate pkg in that same policy. The other alternative is to push a config profile using the built in payloads provided by Jamf to prevent MAU from opening after an installation of 2019 or 365.

We have also seen this with the last 2 package updates for MS AutoUpdater. I haven't filed it, but would be interested to know if others have a case # as well!

Workarround for us start it in the User Context after the Office Install an kill it. We use this command as a Files and Process Command in a Policie.

UserName=$(ls -la /dev/console | cut -d " " -f 4) ; sudo -u $UserName open /Library/Application\ Support/Microsoft/MAU2.0/Microsoft\ AutoUpdate.app; sleep 5 ; killall "Microsoft AutoUpdate"

What I did was go to /Library/Application Support/Microsoft and deleted the MAU2.0 folder and re-install the auto-updater package.

Just pushed 16.54 to a catalina device and a big sur device without the workaround.  I think they fixed it.
