I'm using VS 2010 (.Net 4.0). I cannot add CuteEditor dll to my project file.

 

The designer throws an error:

 
    Protected WithEvents edtTemplate As Global.CuteEditor.Editor 

 

And I cannot use the editor in code behind.

When I add CuteEditor.dll to the project, I get:

 

Error    460    Could not load file or assembly 'file:///C:\Users\rsyed\Documents\Visual Studio 2010\Projects\WebXRM\WebXRM\bin\CuteEditor.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)    C:\Users\rsyed\Documents\Visual Studio 2010\Projects\WebXRM\WebXRM\SGEN    WebXRM
