Currently, if you have the X-Plane demo, when you purchase the full sim you have to re-install it separately. I would recommend you delete the demo folder first, then use the full installer found here to install a full sim with scenery. You'll need your digital download product key email or DVD set to install scenery. We recommend you install only a little scenery at first (maybe a continent or two) and add more later so it takes less time to get flying.
