Heinz Flichtbeil 778 Posted November 28, 2019 Hello, the Box Version of X-Plane 11 don't have a Key. Here the DVD 1 is the licence DVD and must lay in the drive from time to time. The Box Version of XP11 has also no Steam key. This only has the XP11 Steam version. So you have to update the Box Version manually. Use this installer for that. https://www.x-plane.com/kb/out-of-date/ Greets Heinz Share this post Link to post Share on other sites
