Error: Register-spworkflowservice: Unable to Load one or more of the Requested Types in SharePoint 2013

In this blog you will see how to resolve "Register-spworkflowservice: Unable to load one or more of the requested types." error when trying to register workflow service in SharePoint 2013

I was trying to register the workflow service using the following script in SharePoint 2013.

Register-SPWorkflowService –SPSite "http://c4968397007/" –WorkflowHostUri "http://C4968397007.DC07.Loc:12291" –AllowOAuthHttp

I was getting the following error.



I went to Control Panel and uninstalled "Microsoft SharePoint Developer Tools Preview for Visual Studio 2012".

Once uninstalled I opened the new powershell window and tried to register the workflow service, it worked fine.
