Add RadForm problem

[Evren]

When I want to Add RadForm my project coming this error 

Method not found 'Void.Telerik.VSX.WizardEngine.Configuration.ScenerioDefinition.set_PreviewImage(System.String)'.

What can I do?

Hello Evren,

The issue you are experiencing might be caused by a version mismatch between the different Telerik VS Extensions on your system.

I would recommend updating all of your VSExtensions to the latest version. You should be able to do that through the Visual Studio Extension Manager (Tools -> Extension Manager... in VS 2010; Tools -> Extensions and Updates... in VS 2012).

Let me know if that helps.

All the best,
Andrey
