I'll get as insultingly basic as possible, ok. Don't take it as an insult.
Unzip the NO-CD, now it's in a temporary window.
It's a little airplane.
Go into the main (root) folder of FS9 and look for an identical small airplane (DC-3),
It should say "exe" after the name.
Drag and drop it on your desktop. don't click on it.
Now drag and drop the NO-CD one into the space left by the one you just removed.
Take the old one, make a folder for it, name it and put it into My Documents for safe keeping.
Your off to the races.
Lat us know how you do.
