Hi Ryosei,
Welcome.
I don’t understand why installing Simlink should affect FF777 or Avitab.
I suggest :
- See FAQ - Simlink Install and Systray
- In Navigraph Simlink Plugin Settings, for your FS entry press Uninstall Simlink.
- Use Windows to uninstall Simlink.
- If they exist delete folders c:\Users\username\AppData\Roaming\Navigraph\Simlink and c:\Program Files\Navigraph\Simlink
- Download and install latest Simlink .
- Reinstall FF777
Please let us know how you get on.
Cheers
Ian
