Users complain of “autocad crashes when clicking anything” and “autocad crashing when using ribbon”

It seems that a new Computers with the latest version of Windows 10 or computers that recently ran Windows Update for Windows 10 has caused Ribbon crashing issues with AutoCAD versions…

• AutoCAD 2012
• AutoCAD 2013
• AutoCAD 2014
• AutoCAD 2015

AutoCAD starts up, but any interactions with AutoCAD’s Ribbon, Status bar, or Right clicking the Command line causes AutoCAD to crash out instantly with:

Error: Unhandled Exception

We found that this issue is caused by the new .NET 4.7 update.

This update came down as part of KB3186568 and comes as standard in Windows 10 Creators Update (version 1703). Uninstalling all of the affected Windows Updates is not a solution because they are eventually forced down by Microsoft; besides Windows updates usually have security updates which stop hackers from gaining access to your computer so they should always be installed.
