$telerik not found in IIS 7 windows server 2008

Of course, I don't understand Spanish. But following blog was helpful when I got the error installing a asp.net-telerik-web app on IIS 7, Windows Server 2008. The App was running fine in IIS 6, windows server 2003. When installed on 2008, on the client side, got javascript error that '$telerik' not defined, Type not defined etc.

From above blog, I found that the entry under the system.webserver/handlers need preCondition="integratedMode,runtimeVersion2.0" for the Telerik entry. Once I added that the application ran fine.
