Included are two sets of scenery files.
If you only have the LAGO FSE Demo version installed:
Use the ***Dem.SE2 files >> ONLY << (from the 'FSE Demo' folder)
If you have the Full FSE version installed:
Use >> ALL << of the .SE2 files (from both the 'FSE Demo' and 'FSE Full' folders).
Cut and Paste the loose .SE2 files into "Program Files\Flight Simulator 9\LAGO\FSE\Data" folder. That's it.
NOTE: You must at least have, the free Lago demo verion of FSE installed, in order to see the basic scenery. Pick up LAGO's free version here:
