I've uninstalled P3D_V2.1 and am going back to 2.0 which worked flawlessly. Even though 2.2 is about to be released I intend to wait that one out to see if it brings along the same amount of problems that 2.1 did. Now for the problem. . .I have uninstalled the program but when I try to install 2.0 it stops with a message that there is already a newer version installed. I have gone through the registry and removed any references to Lockheed/Lockheed Martin/Prepar3D/P3D. There is nothing remaining, yet the installer is still finding something. . .somewhere. Any ideas as to where else it might be seeing something?
