Olá kaulsa!
Simlink should be installed on the flight simulator computer. It must be configured to find the flight simulator software, and also started. Typically it autostarts.
Simlink can be downloaded and installed separately from here: Navigraph but it is also automatically installed with Navigraph Charts which is convenient for those users who have the flight simulation software and Navigraph Charts on the same computer (which doesn’t seem to be your case).
Connect Simlink and Navigraph Charts to the same Navigraph Account by logging in with your email and password.
If you want to see the aircraft location on your iPad, download the Navigraph Charts app and log in with the same Navigraph Account as you are using on Navigraph Simlink and Navigraph Charts.
Simlink should only be installed on the computer where you have your flight simulator software. It will transfer the traffic to our server via Internet, and then your Navigraph Charts clients will get the aircraft location reports from our server.
I hope this helps. Let me know if you need more assistance.
Cheers,
Magnus
