If you find a machine where the Office Click2Run is out of date, one can force the update.
From an elevated command prompt, run this command:
“C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe” /update user displaylevel=true forceappshutdown=true
*Allow 15-30min for the process to run.
**This will close the office apps (Outlook, Excel, Skype, etc)
