Just a quick note on the 2012 AutoCAD based products, if you have no internet connection on initial start-up, it will crash.
This is because it is looking to connect to the cloud computing server. If you disable 'cloud computing' (with an internet connection) the software will fire up with no issues, you only need to be connected once for this.
Screen shot below of the setting, this is on the Factory Assets tab, as this is in the Factory design suite, it may vary slightly per flavour.
