I already have an FSX-FSX-SE side by side set up using symlinks to point to the SimObjects Gauges Effects etc folders.It works very smoothly no problems whatsoever..Today I just installed p3dv3 and I symlinked it to the FSX folders.It works just fine but I dont know if I can mix p3d gauges etc with fsx ones in the same folder....For the time being I am veeeryyy cautious...I also have an FTX-Orbx setup that is being shared between fsx and fsx-se.I can also symlink p3d to the ORBX folder in fsx BUT...............I dont know how to generate a scenery.cfg file for p3d containing the FTX entries-without installing again ftx.....I could just copy and paste from the fsx scenery.cfg but I am a little uncertain and extra cautious....Not screw things up royally....One step at a time...Lets see.....Good Luck
