Yes it crashes, even if you delete SceneryIndexes folder so that it’s regenerated. But if you install it in game via Marketplace and just go there and start on a parking it works. Buildings are overlapping with Asobo’s default ones when you do that and anyway after next launch it crashes again.
Scenery builder log file does not drop any error. Maybe author just needs to recompile it using latest SDK. I just sent a mail to the author so hopefully he could check this.
