The path from your last reply is leading to the folder with the UI for WPF dlls build for the .NET 4 version. So, if you reference those assemblies in a project with its Target framework
set to .NET 4.0 (or higher) you can use the Telerik controls without any issues. On the other hand the ../Binaries/WPF45 contains the assemblies for the .NET 4.5 framework. In other words, the path from your reply is correct for a project set up for .NET 4.0.
Can you please confirm that you tried the suggestions from my last reply? Basically, you can check the target framework of the project and also if you have installed at least .NET 4.0 on your machine. If this doesn't help you can consider opening a new support ticket from your account and attach your project and the referenced assemblies. This way your case could be tested and if reproduced you can get proper assistance.
I hope this helps.
