Trouble after installation of Navigraph


Please let me know how to solve a problem I am facing now.
I’m using X-Plane11. My aircraft plugins doesn’t load successfully after I installed Navigraph and Simlink.
Installation of those software might broke or deleted some plugins which is needed for loading the aircrafts successfully.
Once I’ve installed Simlink, my PC hit an error, so I uninstalled Simlink.
I can’t move cockpit switches and the Avitab doesn’t work correctly.

I’m eager to enjoy the simulator as soon as possible! Please help me!


Hi Ryosei,


I don’t understand why installing Simlink should affect FF777 or Avitab.

I suggest :

  1. See FAQ - Simlink Install and Systray
  2. In Navigraph Simlink Plugin Settings, for your FS entry press Uninstall Simlink.
  3. Use Windows to uninstall Simlink.
  4. If they exist delete folders c:\Users\username\AppData\Roaming\Navigraph\Simlink and c:\Program Files\Navigraph\Simlink
  5. Download and install latest Simlink .
  6. Reinstall FF777

Please let us know how you get on.


Hi Lan,

Thank you for giving me advices.
I did all of them but nothing has changed, so could you please give father advice to solve the problem?
In addition to FF777, Zibo mod 738 couldn’t load correctly as well, but Toliss a321 has worked normally.
Thank you very much for your courteous support!
