If you go into the FSX main directory there is a folder for Carenado. Go into that folder and open and read the document for what type of RXP integration you want.
After you have done that and know what you want, go to the Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\Carenado PA46_Malibu_Mirage folder. Inside that folder you will find multiple applications for different RXP integration choices. Choose the one you want and run it.
