A new web application security feature has been included since version 5.6.1 to protect the integrity of the workflow parameters exchanged between the WorkflowGen Portal and the web form.

Web apps secure mode activation is defined in the new **Security** section on the **General** tab in the **Configuration Panel**.

**Note:** When web apps secure mode is enabled, all of your Visual Studio Web Forms must have both Assembly files upgraded accordingly. Otherwise, the web form will raise the .NET error `Unable to read the form data from the XML file.`

The requirements for existing clients with Visual Studio-based webforms are:

#### WorkflowGen version 5.6.3 and earlier

Upgrade `WorkflowGen.My.dll` and `WorkflowGen.My.Web.UI.WebControls.dll` to version 2.3.4 in your Visual Studio Web Forms `\bin` folder.

#### WorkflowGen version 5.6.4

Upgrade `WorkflowGen.My.dll` and `WorkflowGen.My.Web.UI.WebControls.dll` to version 2.3.5 in your Visual Studio Web Forms `\bin` folder.

#### WorkflowGen versions 5.7.x and 6.0.x

Upgrade `WorkflowGen.My.dll` and `WorkflowGen.My.Web.UI.WebControls.dll` to the same version found in your WorkflowGen `\wfgen\WfApps\WebForms\Bin` subfolder.
