If, after the product has been installed, and there are parts of the panel missing... this indicates that SIMCONNECT is not fully installed.


These are the SimConnect installers you should try to run (note your P3D location may be different)...

You need to drill down to the lib folders in each, and then you will see the SimConnect.msi installer. No need to do the different language version installers. Just the main ones. Try FSX-SP2-XPACK first, then the others.


MCP blank, weird flap indication, gear up level when gear is down, flickering N
2 indication. Uninstalled all 4 simconnect modules and reinstalled from the SDK folder in FSX-SE.

Simconnect files: YOUR_STEAM_FOLDER\SteamApps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces
