Thank you for the additional information provided.
If you just want to look at the source code of our examples, you do not need to download the source for the entire suite. With the installation of the suite we also deploy a solution containing all examples from our demo application(s). You can open these solutions from your Start Menu (Start Menu > All Programs > Telerik > UI for WinForms >
Examples > C#/VB for Visual Studio 2010). The demo application solution is called: Open C#/VB Demo Application in Visual Studio - UI for WinForms.
All these are available in the Telerik folder in Program Files (C:\Program Files (x86)\Telerik\UI for WinForms Q3 2013\Examples
) as well.
Now, to the errors you got. I have installed the Q3 2013 SP2 suite on a clean machine and I have downloaded and extracted the source code to the same path as yours and I got some about 88 errors (different than yours). The errors on my end were caused because the file tree in our solution is quite deep, while Windows supports up to ~260 symbols path, so files with longer path were omitted. Once I extracted the source to C:\WinForms\ instead of the path you used I was able to build the source with no issues. Please give this approach a try.
I hope this helps.
