HJG Aircraft in FSX HELP?

I recently visited Air Force One at the Ronald Reagan Presidential Library, now I want to fly it. HGJ has the very plane on his site, part of Simviation. However, Tony Madge, from the site said that someone here could help me with installing the plane in FSX. Here's my Goal, Install the plane it's the 1981 VC137C 72-7000, the panel, I believe it's the 137b/c advanced and the correct sounds for it, not sure which ones. (as wel as the correct Core files). I've tried several times but the plane never shows up in FSX. I need a simple easy to follow direction in which files to download and how to make it all work in FSX. I'm not a young pup so please make it simple!
Any help would be GREATLTY appreciated.
