I downloaded the Free Version of the GTN750 a while back and have decided to upgrade to the Premium Version. I purchased the upgrade which gives me an activation key however try as I may I have seen nothing in the Installation Documentation that refers directly to how to apply the activation key.
I loaded the Sim and selected an airplane and selected the GTN750, however it is still the Free version with most options unusable.
