I wanted to make a CargoLux repaint for GSX using P3Dv4, however downloading the kit, I cannot choose P3Dv4. Using the "Brose sim" button I tried to select the P3Dv4 folder (in my case: "C:\Program Files\Lockheed Martin\Prepar3D v4") however that is a no go as well ("No supported sim found in:...").
