I started version 1.2 on Windows 10 for the first time, having moved the folder into my Program Files folder, and it got to the splash screen before crashing back to the desktop. On my second attempt I ran it as an administrator and it started and worked correctly. I don't know if the admin did it or it just started the second time. Either way 1.2 is working okay at the moment. BTW - this is a really fun piece of software. Sort of like Bryce Lite - very relaxing and recommended to anyone who likes to fool around with 3D landscapes etc. I would love to see editable terrain and the ability to import 3D objects.
