Nintex Workflow 2010 crashes IE unexpectedly during events such as when a new string variable is created in a workflow

What?

Nintex Workflow 2010 crashes IE unexpectedly and randomly when certain actions are performed such as when a new string variable is created in a workflow

Why?

Nintex Workflow 2010 at the time of posting this blog is not fully compatible with IE 10. It works perfectly with IE 9 and IE 8.

How?

In my case, an automatic update from windows has updated IE in my machine from version 9 to 10 and as a result, Nintex Workflow 2010 has started to crash IE unexpectedly.

Check the version of IE in your machine to see if it happens to be IE 10 and if you are keen on getting Nintex 2010 to work, you can either use the compatibility mode settings in IE 10 as suggested by someone from Nintex in a post.

It did not work for me. So I had to uninstall the Windows Update that updated IE 9 to IE 10.
You can do that by going to Control Panel > Programs & Features > View Installed Updates.

Under the group "Microsoft Windows", you should find "Internet Explorer 10". Uninstall it and Nintex Workflow 2010 should work fine.
