When trying to run a simple grid I get the following error. It occurs for any controls I use.

Unable to create type 'telerik:RadScriptManager'. Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

<form id="form1" runat="server">
Line 13:     <div>
Line 14:         <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
Line 15:         </telerik:RadScriptManager>
Line 16:         <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True">

It works fine on my development box with Visual Studio 2005, but on the web server I get this error.

I have:
- Installed the compenents on the web server using RadControls_for_ASP.NET_AJAX_2009_1_311_trial.exe
- Used gacutil to add Telerik.Web.UI.dll and Telerik.Web.Design.dll to the GAC

There seems to be a recurring problem with this on the forum but I haven't found any successful solutions.
