If you have FSX/FSX-SE installed, then you can install it there, then copy everything across to *P3Dv1/v2/v3.

The best way to do it, if you don't have FSX/FSX-SE, is to do it as I said in my reply directly above your post. ;)

*I doubt it will work in P3Dv4, as the P3D versions of the Captain Sim 727, 737, 777, and L-1011, do not work in P3Dv4.
