Hi folks , Just an update on my problem with the T7. OK I managed to clear the unhandled exception by removing the two liveries I had installed via PMDG Op Centre. I was then able to uncheck the passenger tick box for the T7 in the config menu and all works ok in the config menu, all be it I cannot have passengers seated, I`m ok with that at the moment. I did discover something else whilst playing about. If I had any liveries installed, from the Op centre, other than Singapore Airlines, China Eastern, Phillippine Airlines, Turkish Airlines or United, then the unhandled exception would occur. Also If I then loaded up one of these "working" liveries with the seated passengers enabled in config, some of the crew and all of the passengers have pink textures when seated.
I realise I need to sort out my MSFS file location issue but its too late in the game to mess about with that, I`m happy to just fly and when MSFS 2024 comes out, I`ll sort out all the bells and whistles that add to the sim.
Update: I confirmed that my problem is definitely caused by long file name location of my community folder. The PDMG installer doesn't install the "Behaviors" folder when installing liveries to the liveries folder, because the location file name is too long. was confirmed by selecting the PMDG livery in the sim and running the GSX seated passengers option in config, GSX worked flawlessly, seated passengers, no pink textures etc.I found out this is because the PMDG livery is contained within the aircraft folder itself, not the liveries folder so the file name location is not as long but as I said I`ll hang on till I have to install MSFS 2024 to sort it out as the only way to solve it is to reinstall MSFS 2020 in a different location with shorter file name. Not a problem for me at the moment but just thought I`d let people know my findings.
