Yep.
Right click on the desktop, click new, then shortcut. Copy the URL C:\Program Files\Logitech\Microsoft Flight Simulator Plugin\LogiMicrosoftFlightSimulator.exe”
Save that, then edit the properties of the shortcut, goto shortcut, select Target, and then at the very end, add --force --run
As soon as I did this, my Saitek Panels are now at least lit up, and I don’t get the argument error anymore.
