Hi, Wilde.
You'll find in your zip folder the main folder, then if you click on it, the two folders named scenery and texture. Go back to your main folder, and stick that into your C-Program Files-Microsoft Games-FS9-Addon Scenery folder.
Then, start flight sim. On the main menu on left, go to Settings. You'll see a box on the bottom named "Scenery Library". Click on it. Then on the right, you'll see somewhere in that stack a box that says "add area". Click on that, then go to "addon scenery" and look for the folder you put in in the first step. Then close flight simulator and restart. You're good to go.

The subfolder "scenery" in the Addon Scenery folder is for AFCAD files and that of the like.
The texture folder is for all those surfaces that are shown in the scenery package, so everything dosen't show up grey.
Hope this helps.
