I bought AutoCAD LT 2013 earlier today, downloaded the installer, and when the installer was finished I selected "Open AutoCAD LT 2013 English for Mac OSX"
A window popped up with an Open button. When I clicked it, the screen flickered a little (like it was loading or updating) then the same "Open" window popped up. I clicked it again and the screen flickered again and then nothing happened.
Is there a reason that AutoCAD won't open?
