You can’t open the application “AutoCAD LT 2016” because it is not responding.

[Anonymous]

Frequently I cannot open AutoCad Lt for Mac and get "You can’t open the application “AutoCAD LT 2016” because it is not responding". This occurs even when I try to "Remove" AutoCad so I might reload the application. If I try to shut down the Mac I have to force quit AutoCad.

I would try and run a clean uninstall. 

You could use this AKN article and or this Uninstall OS X Daily guide.
