seg9585 did you manage to fix the issue? I happen to also have the exact same issue and the same generation of x1 carbon (but with a i7 7500). Cura crashes and closes at the user agreement dialog box after I upgraded to Cura 3.6 from Cura 3.5. Cura 3.5 and before used to work but now it doesn't. I tried version 2.7 too, but now it closes a few seconds after launching. Before trying any version, I would uninstall, delete the program folder and clear Cura folders in %appdata%, still doesn't work. Would appreciate any feedback.
