I am trying to run the demos on the telerik site but each time I try to do so, I get an error message about not being able to load file or assembly 'Telerik.Windows.Controls' version 2010.2.714.1040 (see file attached). I have telerik 4 installed on my machine and I was able to run these demos not so long ago (in fact, last week). I am confused... I have version 2010.1.603.1030 of the file. A co-worker has exactly the same file as me and he can run the demos.
Can someone help me with this issue?
