Launchpad stuck 'installing'
I am running Catalina and had to subscribe to Microsoft Office 365 as Microsoft Office 2011 is no longer supported.
Since Installing Microsoft Office 365 there is a blank installation bar under the Launchpad icon in the dock and when I hover over the icon it shows 'Launchpad Installing'
When I go into Launchpad one of the icons to do with Microsoft ( "Microsoft ...ianSpeller") shows an almost complete installation bar with "428,1 MB of 428.1 MB" underneath.
Microsoft Office 365 applications appear to be working
How can I resolve this Launchpad hang?
