Problem running AutoCAD 2013 or 2011 on a Lenovo W530 (Win7)
In AutoCAD 2013, when entering a command on the command line, it will not execute after hitting enter. Ribbon buttons appear inoperable also. Strangely, I can enter commands on the Dynamic Input cursor. Most basic commands appear to work, like line. But certain commands that require a dialog box, such as Xref, Plot or Properties pallette will crash AutoCAD. The Layer command gave an unhandled exception because of a null value in the JIT debug.
It does seem to point to .NET install problem. I have uninstalled and reinstalled .NET 4 Client and Extension without success. I have not tried C++. I would like to see if I can narrow it down to a single component because I've seen this problem before and I want to elimiate the source. Any recommendations?
I would uninstall AutoCAD and reinstall it using a browser download. You can download it from the Virtual Agent (#3) here:
I would also re-install your video driver. The instructions are noted here:
Typically, JIT errors are video driver related.
