The professional use version of "X-Plane" includes all the features of the personal use version, but has more capabilities depending on the license used. A commercial license can be obtained which allows one to use "X-Plane" without being tied to a specific computer via e.g. a disk or USB key. The commercial version also supports "kiosk mode" in which "X-Plane's" settings can be locked via password protection. The professional use version can also allow one to generate revenue from X-Plane related content.
