Just as an update.....after installing aircraft into P3D it seemed to all work pretty good except Prepar3D gives a list of errors and after just starting the load of the PC-12 it thru about 285 errors and that was without starting engines or anything. lots and lots of scripting errors. I can not imagine what that log would look like after a 3 hour flight. This happens even with the updates from the forum. Not sure I would recommend this pc-12 thing. I would think all those errors can not be a good thing. YMMV
