Since the beginning I was using default "Launch on computer start " option. But since I had 2 times this program in an unusable state (impossible to select any buttons with the mouse, on the window), I had to re-install the program (version 1.0.12) to solve this curious problem.
So, I decided to disable this option and now, obviously now, I can see the program loading (which wasn’t the case before) and see that it display a light-blue screen with the error message “no simulator detected” ?!?
But, this error screen seem incorrect, because I have all categories & buttons as usually and they work, at last for now ! I even tried to remove the data’s from my PMDG 737-700 and then, to install again and this was performed without any errors ?!?
Do-you know what happen here ?
