Question: Upon opening a workflow in SharePoint Designer 2010 I receive the following notification in SharePoint Designer:

> 
> The list of workflow actions on the server references an assembly that
>  does not exist. Some actions will not be available. The assembly
>  strong name is Microsoft.Office.Workflow.Actions, Version=14.0.0.0,

>  administrator for more information.
> 
> 
> 

I'm running SharePoint 2010.

Does anyone know how to solve this notification?

Answer: 
Go to your hive folder:

Then into Template\1033\workflow

and find WSS.ACTIONS

Inside there will be a reference to a custom DLL, find it and remove it and your designer should start working again.

Make sure you take a backup of the file first.

Happy hunting.
I think the quick fix for your problem is to [download the assembly](http://www.zhaodll.co/m/20130509/194067.html). and deploy this in the gac using [GACUTIL](http://msdn.microsoft.com/en-us/library/ex0ss12c%28v=vs.80%29.aspx)
