When launching FSX 2020, you may see one of these errors:
“License Validation” when trying to access a course or range
“License Validation An Unexpected Error Occurred”
These errors usually mean FSX couldn’t validate your license because it couldn’t reach our servers or there’s a configuration issue.
Internet connection
Make sure your PC has working internet before launching FSX 2020. The app must contact Foresight’s server at startup.
Check for network blocking
If you do have internet but still get the error, your ISP or network might be filtering or blocking communication to our servers. Comcast/Xfinity is a frequent culprit.
Credentials & license validity
For the “Unexpected Error” version, verify that your username/password is correct and that the license key you entered is valid for FSX 2020. Also check that the license isn’t tied up with another installation (e.g. FSX Pro iOS).
Deactivate and re-validate license
If the above checks don’t help, release or deactivate your FSX 2020 license and then reapply it to the PC you’re using.

Q: Why does FSX work if I lose internet after launching?
Once FSX reaches the main menu, it doesn’t need constant connectivity. The critical point is the initial server check at startup.
Q: How do I know it’s not just a corrupt install or license file?
If other customers with the same license are working and your credentials are correct, network blocking is the more likely villain.
Q: What should I ask my ISP or support if it’s blocked?
Ask if traffic to Foresight’s license server domain is being blocked or filtered. For Comcast/Xfinity, we have specific guides to allow it.
Q: Will reinstalling FSX fix this?
It might if your install is corrupted, but usually license validation failures stem from network or credential issues. Try the checks above first.
