I have FS2Crew for both the PMDG 737 NGX and the 777. I initially installed for P3d since that is all I had running. I've expanded the system and now have FSX installed on a different drive. I have compared the panel.cfg between the NGX for P3d and FSX and added the entries for FS2Crew in the FSX version. They were identical other wise. I also mapped the autofeather key in the FSX NGX as specified in the Main Ops Manual.
Unfortunately, I still can't get it to work in FSX although it still works in P3D. So, is it possible for the same FS2Crew installation to work for both FSX and P3D? If so, what step am I missing. Or, do I need to do a separate installation of the same FS2Crew software to a different location to make it work for FSX while still having it work in P3D? I'm a big fan of FS2Crew and plan on trying to do the same for the 777 and later the Airbus.
