I had had a persistent problem with repeated requests for Activation; this occurs every time I start the sim (Prepar3D v4.3/WIN 10). Although it appears to work properly, it's a bit of nuisance. After reading various threads about the problem, nothing has resolved it. The things that I have explored include (1) AV and firewall exclusions (settings), (2) GSX uninstalls and reinstalls, (3) checking possible compatibility mode settings in the Registry (none), and (4) running the system in Window versus Full screen for the registration. I have purchased a number of FSDT sceneries, and they have installed and registered without a problem (including GSXL2). Any suggestions would be greatly appreciated--Thanks--
