I have the RealAir turbine duke V2 The installer works perfectly with fsx se you just need to show it were it is in your pc and same for the config app it will say that it hasnt detected fsx you show it were it is and it will work but everytime you open it it will give you a warning saying that it thinks the location is faulty but ignore it it works i checked it even changed settings for cold and dark works perfectly for me
