Quit looking :emotion-1:  I found that I could download it again from the support site, and that fixed the problem.
I just noticed that when I click on MY DELL on the Windows 8.1 Start Screen, I get: "License Authentication Failed.  This version of Dell Support Center is not licensed to run on this system. " I think this started after updating from Windows 8 to 8.1. Any ideas? p.s.  It's been so long since I've run this app, I forgot what it does.
