Reinstall Pace
Reinstall eLicenser
 
Pace installer doesn't always work. Looking thru the folder I found you can just install the drivers.
I'm lucky I don't have issues with eLicenser.  Pace it's usually installation problems.
 
Anyone else want to add "constants" when it comes to authorization or reinstallation.  Should be a sticky for these.

Pace doesn't seem to have an issue for me. I didn't do a reinstall of it, and it was happy as soon as the system came up. I have a hardware dongle though, not software licensing. eLicenser needed a reinstall to make it shut up about the broken software licensing, but the hardware worked without reinstall.
