I have just updated to the latest version of Office 365 for Mac today. The update process went fine, and all Office apps work OK as well
The problem that I found was: when I click Herp - Check for Update, Office Autoupdate won't open. A dialog read Microsoft Autoupdate cnnot be open: Microsoft AutoUpdate might not be properly installed on your computer. To restore it, reinstall your Microsoft application.
When I open Microsoft AutoUpdate directly, it open and run properly. I do check for update and stated that all are up to date
This happen for all Office apps. Fix and support please. Thank!
