Hi, I'm new here.
Today I'm experiencing a bad issue for the first time.
Excel hangs at the startup window indefinitely - like forever.
This happens when I launch it from the programs (Windows) menu as well as when I click on a file name (ANY .xlsx file).
All other Office programs work fine.
I have restarted the pc two times to no avail.

What can it be?
