Easy Fix guys
I think it is mainly a problem if you don't have FSX installed

Hello Brendon Most likely it is the following issue: If there is no FSX installation on your PC, you might need to run the following installer, found in your Prepar3D root folder: \redist\Interface\FSX-SP2-XPACK\retail\lib\SimConnect.msi in order for the Q400 to be able to function Thank you, With best regards, Oleksiy Frolov
