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.

Hello simonbooth,
I had discovered this issue on my own over the past few weeks and had successfully downgraded from the Windows 10 Creators Update (1703) back to Windows 10 Anniversary Update (1607). Today I got another three updates:
One for Adobe Flash Player
Update for Microsoft Windows (KB4035631)
Security Update for Microsoft Windows (KB4034658)
Now I’m having the same problem. I discovered KB3186568 installed again and uninstalled that update successfully. I double checked and I am still running on Windows 10 version 1607. I tried “repairing” Autocad and ensured that I have all the proper updates for it, and restarted a few times. I even tried running it in “Compatibility mode” for Windows 8 and 7. None of these worked, I still can’t access the Ribbon without it crashing.
I’m going to uninstall the two latest updates for now, but do you have any other information to add that might help me avoid this problem in the future? I rely on Autocad for my business (obviously), and I can’t afford downtime with it right now.
*Update*
I cannot uninstall KB4035631, Was able to uninstall KB4034658. This seems to fix the issue for now.
Is there any indication that either Autocad or Windows will fix this issue or to I need to keep uninstalling windows updates forever?
We are actively trying to solve this issue for our customers, but there is no solution other than the one we documented (and now yours to uninstall KB4034658).
In the meantime, this issue is really down to and caused by Microsoft; everyone who runs into this issue should complain on their forums.
I am trying to uninstall updates and it is not giving me the option to “uninstall”. I did a system restore back to a date prior to update.. Windows has since done another update and I am experiencing the same problem. How do I suspend updates entirely
We are currently working on a solution to this issue for everyone. Can you contact Longbow Support so that their engineers can review your specific issue please? Please contact at https://longbowsoftware.com/contact
Solution is now ready, see above…
Simonbooth, Which portion of your write up above (originally posted Jul 25) covers the updated “Sep 3, see above” solution you are referring to? An auto update KB3186568 on my computer today caused the very problem discussed. Are you saying that installing the Longbow converter app (“https://longbowsoftware.com/downloads/ols/categories/longbow-converter”) will fix the problem? … or do I have to uninstall the updates (KB3186568, KB4033637 and KB4034658) that automatically updated on my computer today?
Thanks to your valuable posting.
Hi T-Sis,
We found that there is a combination issues which must be processed in order, the latest version of our Converter tool handles these issues for you (instructions above). If you still have problems, let us know and we will look into it further for you.
I got it working by following the instructions.
Followed the instruction step-by-step and AutoCAD worked again without error after activating a ribbon command.
I was in a digital swamp, causced bij an update of Windows 10 and the netframe 4.7. Autodesk did not feel responsible to distrusted a fix. Installed the latest version of the converter, had some questions and got a great support of Longbow. Smart program and great service.

I am attempting to uninstall updates and it is not giving me the alternative to uninstall. I completed a framework reestablish back to a date before refresh. Windows has since done another refresh and I am encountering a similar issue.
You don’t need to uninstall the updates… Simply uninstall your existing AutoCAD, then reinstall using our Converter App – it fixes the issue for you automatically and allows you to use Windows Updates again
How can we achieved this on a windows 10 system PC, without uninstalling the existing version of Autocad. I am using Windows 10 Pro on Intel Celeron PC.
Yes… Using the latest version of the Converter, you can simply fix the installed program files…
In the Converter, select the 3rd tab named “Old AutoCAD program Reviver”, pick the acad.exe folder, then click Fix Old Program… As long as no errors are reported, you should be good to go.
If this problem is comes with a windows update, Microsoft should be notified regarding this, so that they can solve this problem by including an additional update with the next Windows update release. Hope this will be solved soon.
It is solved, please see solution above
When this problem come with original licensed version of Autocad and if we use “Longbow Converter App” for solving this issue, how can we use the original Autocad License key when re-installing the application ?
We have updated the blog post, please see above… You no longer have to uninstall and reinstall, just use the Converter App to fix the existing program files!
Thank you for creating such an awesome app “Longbow Converter App” for eliminating Auto cad Crashing. Let me know does uninstalling and re-installing Autocad will cause losing my old drawing templates in Auto Cad? And if it is, how can preserve them before proceeding ?
