I'm lost guys! Im looking for a good flightmodel of b737ng and I deceided to give posky 737-800 a try but Im stuck when trying to install it.

From the site I can find different livaries (it seems to be the whole plane with livery and not just the livery), basepack and modelpackage.. What do I need to download?

I would love to have the SAS livery (Scandinavian Airlines). I tried to download the livery but it doesnt come up in FSX. I tried to change the alias in panel and sound config with no result.

How should I do a proper install of posky 737-800 SAS livery?

Would appriciate if someone could explain it to me.

Im using FSX.
