I have already activated X-Plane 11 several times, but from time to time the program again requires activation. There must be a way to record serial number and activation to avoid successive insertions that hinder the use of the program.
After entering the serial number and receiving the activation number, the screen allows the options: "Copy", "Next" or "Back" and none of the options gives continuity to the recording of the activation. My Windows 10 system works fine on all other applications.
If anyone knows the solution, please let me know.
