I am now at raycar's point. I found an error with my Windows 10 (Thanks Microsoft). Now that it's corrected, all the parts show up. But I also see the exhaust on the wrong engine. I can live with that. Beautiful aircraft.
I installed what looked like a beautiful aircraft judging from the screenshots. However, I noticed some parts were missing. Namely the vertical stabilizer the engines and props and part of the landing gears. I wonder if there is an alpha channel problem. John B Loney Jr
