This is what I did. I downloaded AGExcl_3x and opened it. I have an Addon Scenery folder directly under the Microsoft Flight Simulator X folder. It contains two folders, Scenery and Texture. So I copied over the scenery files from the AGExcl_3x and placed them in the Scenery folder under the Addon Scenery folder. Then I ran the program. When it started to run I got the "rebuilding scenery..." so I thought it saw the scenery. But when I went to VNLK near Mt. Everest I still had trees near the end of the runway. I did not ses a difference. I even went to the scenery library and moved up the Addon Scenery to the top. When I went back to the program it reconfigured and it was still the same. What am I doing wrong? I am not good at adding scenery and stuff and I saw the post about the trees at the end of the runway so I thought it would help. If I DID do it correctly, could it be possible I may need the 5x version?
