Telerik and jquery
I'm not sure whether the approach shown by andreas will help you. As you can read in this article (or here), telerik already does something similar "to avoid compatibility issues with applications which already use (other versions of) jQuery".
I did it by telling Telerik not to register his version of jQuery at allIt can be done once for the site in _Layout.cshtml file
in head section I am loading needed versions of jQuery scripts manually
<script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")" type="text/javascript"></script>then before
@(Html.Telerik().ScriptRegistrar().DefaultGroup( group => group.Compress(false).Combined(false)) .jQuery(false) .jQueryValidation(false))
