Error When Publishing Workflows in Dynamics CRM 4.0 (an error occurred when the workflow was being created. try to save the workflow again).

A couple of days ago I received the above error when trying to publish a workflow in CRM. After some searching I found out that this error may occur after installing Update Rollup2 Update Rollup2 For Microsoft Dynamics CRM 4.0  .
What actually happened is the the following line has been removed from web.config for CRM Web Application.

<authorizedType Assembly="mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Namespace="System.Globalization" TypeName="CultureInfo" Authorized="True"/> 

So what you need to do is adding the above line under <authorizedType> Node in web.config  and execute IISReset /Noforce .

That’s it.

Mouse Over the Rollup Version or KB Article Number to go to the appropriate Page.

To determine what is your current Rollup Number in CRM Web Client or CRM Outlook Client go to:-

Help > About Microsoft Dynamics CRM .

Also if you noticed a different number than the above mentioned, than you've likely installed a Hotfix Click here to Go to the Hotfixes Page.

Of course I will keep this Post Up-to-date with the Upcoming Rollups .

Happy updates .
