FSX -SP2 Ultimate Breaks SimConnect communication with all PMDG aircraft

Recommended Posts

FSX SP2 Breaks SimConnect communication with all PMDG aircraft.


When a PMDG aircraft (777X or 737NGX) has been loaded in the simulator (FSX SP2), and has finished (the aircraft) initializing itself, if Multi Crew Experience (Ultimate Edition is launched, an OK button messagebox with the following message:


Titlebar -> "fsx.exe - System Error"


Message -> "The program can't start because SimConnect.dll is missing from your computer. Try reinstalling the program to fix this problem."


Button(s) -> "OK"


for 2-3 times.


When MCE finishes loading, the following happen:


- all commands to the FSX interface (they are aircraft-independent) work normally (for example, given the command "I have the radio" the FO replies ("Yeah, you handle the radio).




- all commands specific to the loaded PMDG aircraft, while acknowledged from the FO, and confirmed as implemented from the FO, in fact they are not carried out

(for example, given the command "Set heading Two-Seven-Zero" the FO replies "Setting heading to Two-Seven-Oh", and after a couple of seconds he also says "Set", but the actual heading dial has not changed at all)


The same behavior occurs with the PMDG MD-11X, with the only difference that the messagebox is not displayed.


Above behavior happens only with all PMDG aircraft.


Also, I know that SimConnect is working properly, because when pressing "B", I will see the QNH changing in all the displays (from the standard 1013), from data supplied by the running ActiveSkyNext.


Other aircraft (SimCheck Airbus A300, Aerosoft Airbuses A318/19/20/21) work normally.


Going back to MCE Ultimate Edition, everything works flawlessly.


Simulator version is FSX SP2.


All PMDG aircraft are the latest versions.

How refreshing that FS++ are prepared to admit a mistake.


Most software developers would blame an unforeseen anomaly...


Another reason why MCE is the best! :smile:
