    Our application is hosted on IIS7 64-bit, It is working fine on IIS6 but from IIS7 we are facing some issues:

    When trying to execute a code which has radconfirm we are getting following errors:


    •  ASP.NET Ajax client-side framework failed to load
    • 'Sys' is undefined
    • “Telerik.Web.UI” is undefined


    I tried with all steps mentioned in but of no use.

    Please help.

    Hello Sudhanva,

    Can you please verify that you granted permissions for all users to operate with the Telerik.Web.UI.WebResource.axd handler? How to do that you can see from the relevant paragraph of this article in the product documentation.

    You may also try replacing temporary RadScriptManager with asp ScriptManager or set its EnableScriptsCombine property to false to compare the results. Additionally, make sure you use the latest version 2010.2.713 of the suite.

    Best wishes,
