Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have had the same problem, the installer stuck at 2% the entire night. I am providing a version of the fix that seems to work after hours of tinkering around.
- Task Manager --> end all versions of Microsoft Installers Click to Run, etc.
- open services.msc --> locate Microsoft Office Click-to-Run Service --> Stop.
- Execute the installer again --> this will cause the status bar and the Windows installer banner to come up --> you will also notice the service has been started again ( as this was and should remain in automatic)
- Hopefully you will zoom past 2 PC. and eventually complete.
Hope this helps
