Add-ons stopped responding? Regenerate wxstationlist.bin

Delete the wxstationlist.bin file so the simulator rebuilds it and SimConnect add-ons like ChasePlane start working again.

This article covers the following platforms

  • MSFS 2024
  • MSFS 2020
  • ATS
  • FSX
  • Prepar3D

With some add-on combinations, the wxstationlist.bin file can make SimConnect applications (the way add-ons like ChasePlane talk to the simulator) stop working properly. Delete the file and the simulator will rebuild it. ChasePlane does not modify this file, so it is not the cause of the issue.

  1. Shut down the simulator.
  2. Open the AppData folder for your simulator:
    • %APPDATA%\Lockheed Martin\Prepar3D v5
    • %APPDATA%\Lockheed Martin\Prepar3D v4
    • %APPDATA%\Lockheed Martin\Prepar3D v3
    • %APPDATA%\Lockheed Martin\Prepar3D v2
    • %APPDATA%\Microsoft\FSX-SE
    • %APPDATA%\Microsoft\FSX
  3. Delete the wxstationlist.bin file.
  4. Launch the simulator.
