For some reason when I double-click on an Excel file in Windows Explorer (or
try to open an emailed file directly from the email) it no longer opens.
This suddenly started happening - or not happening - last week and I have no
idea why. I can still open from inside Excel with File, Open.

Any ideas on how I can fix this?
