Same here. I have used the eLicenser help tool to re-registered my eLicenser installation and activated the newly provided SpectraLayers key, none of which has helped. Below are the two error messages I receive.
I was able to resolve the problem by launching SpectraLayers as an administrator. Just right-click in the Start menu and select "Run as administrator". After doing that once I am now able to open it without elevating to admin.
