and fyi i install the GSX in P3d folder is the cause of the issue because i already install it once in C directory
Don't install GSX inside the simulator.
- Uninstall it, and
reply YES to the question "Do you want to remove the Addon Manager ?. This will allow to choose a new folder for the next install.
- Reinstall it either in the default location, or any other drive, but NOT inside the sim.
- If you have other FSDT products, you must reinstall all of them. They will all end up under the folder you chose in the reinstall step.
