Check Your X-Plane Installation:
There may be an issue with the x-plane_install_11.txt (or x-plane_install_12.txt) file located in your %LocalAppData% folder.
This file should contain a single line with the correct path to your X-Plane installation. We’ve found that, in some cases, X-Plane may fail to update this file with the correct location after a re-installation.
To resolve this, please verify that the file contains the correct path. If it does not, you may need to update it manually.
Additionally, the X-Plane launcher should indicate that X-Plane has been successfully connected on the launcher window bottom right corner.
Also note that there will be no specific bindings listed under "X-Plane Assignments" because the controls are managed directly through the launcher.
