  After I publish a WPF application and then try to install it . . . I get the following error:
  
  Unable to install or run the application. The application requires that assembly Telerik.Windows.Data Version 2010.2.924.40 be installed in the Global Assembly Cache (GAC) first.
  
  I am using Version 2010.3.1314.40 . . . so I am not sure why an earlier version is required. In the properties of Telerik.Windows.Data,
  Copy Local is set to true. So if this copies the assembly to the client machine that I assume this should resolve the issue, but it has not.
  
  I have attached an image of the full properties of Telerik.Windows.Data.
  
  Please help if you have any ideas.
  
  Thanks.

  My problem is resolved now.
  
  One of my projects in the deployment had just one of the telerik dll references pointing to a folder outside of our "Shared Libraries" solution folder. Once this was fixed, the deployment was successful.
  
  It's weird because it caused all of these Telerik version errors.. and was a bit misleading.
