I just installed ACAD MEP 2015 (via Building Design Suite Ultimate) and AutoCAD won't start, but Revit starts just fine.
There's no particular prompt, nothing "loading" in the splash - just a straight up crash. The ACAD process in my task manager has completely stopped, and no pop up indicating a crash/"ACAD has stopped working" message.
I tried running a repair - didn't fix anything.
Has anyone encountered this yet? Any fixes?
