Now you didn't ask that. That's a whole different matter.

It should come with some instructions. Read those and give it a try. There's some tools included to get the location and orientation right then you use another tool to create a .bgl file. When that's done you just place it in the folder they provide with the demo hangar. You will need to install the demo hangar first and activate it like any other add on scenery.
Edit:Just installed myself. I had it on the old computer but haven't moved it over. You will need to install the base package by hand. It doesn't seem to find the sim correctly and creates it's own folders inside the sim folder. Just install from the .exe to a temp folder and then copy the files to where they are supposed to go.
Start up Fs9 and activate the scenery. You will find the instructions in a .pdf file in the scenery folder that will give you a step by step for putting your hangar where you want it.
