I have a problem with the airplane installers. In the past, i used to play FSX, but i removed it a few month ago. Then, i bought P3D. When i try to install the airplanes, the installer select "Microsoft Flight Simulator" option while saying "Detected!" and don't let me change to "P3D" option.
I am sure i have removed all files related to FSX but the installer don't let me install it for P3D.
