Sorry but you've still lost me. Is this an Express or BaseCamp issue you're having? Also BaseCamp doesn't load internet explorer so I don't understand that comment.
I run both Express and BaseCamp with Win10 and everything works perfectly. What exactly are you trying to do?
Things have improved I deleted everything and reloaded Garmin Express and now Unlock Maps finds my device and I can enter my device serial number but I have no Product Key/Coupon Code to enter. How do I get a Product Key?
