Scenery can be added or removed at any point in the future by re-running the installer. Insert Disc 1 if you have the DVD set, but if you are using a digital download product key, X‑Plane should remember it. If not, enter your product key when required. When the X-System installer comes up saying “You already have X‑Plane 11 installed on this computer,” click the Add or Remove Scenery button. You can read more about installation of X-Plane here.For "key/activation" problem you can check your internet connection. You should be connected to the internet when X-Plane tries to verify the key. If it happens again you can attach a copy of the log.txt and contact support at [email protected] or you can file a bug report here. You can also read more here.
