Nintex Workflows 2010 stop working after Security Update (KB 4022207 & KB 4032215)

Hello Nintex Community,


we installed the mentioned Updates and the Workflows stopped working, they start and immediately run into an Error.

It's not possible to edit specific Actions, like Set Field Value, and existing Workflows can't be published.


Nintex Support mentioned the following workaround:

A workaround is to add the below line to the <targetFx version="v4.0"> node under the <authorizedTypes> node of the web.config file <authorizedType Assembly="System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089" Namespace="System.CodeDom" TypeName="*" Authorized="True"/>


But that seems not to be working, after the Updates are installed, the Problem remains.

Any suggestions what could be wrong?



Windows Server 2008 R2 Enterprise - Service Pack 2

SharePoint 2010 - 14.0.7175.5000

Nintex Workflow 2010 -
