BIG MISTER I will give it a try....
My questions is which version of FS are you running and what are your computer specs. The biggest problem with installing packages like this is the computer, while meeting the minimum specs shown on the box will not be able to handle the program.
Wilco Pilot in command 737 comes on a DVD and has a lot of extra stuff on it that is try before you buy. There is some free stuff on it too, like the Spitfire, but avoid the trial ware.
To Install, just place the DVD in your DVD drive and install it. It takes I think three clicks and you are ready to go.
Make sure you read the manual that came with the software, all 68 pages, to get the best out of the package.
