AjaxPro Not Running On .Net Framework 4.0 and Server 2008 / IIS 7

I'm using AjaxPro & AjaxControlToolkit in my project. My project is normally running on Server 2003 with IIS 6. But when i loaded my project on Server 2008, i'm getting "AjaxPro undefined" error. My project is working .Net Framework 4.0 Classic mode.

I tried this but my project isn't working still.

I found this code on web and tried this;

<location path="ajaxpro">
    <system.webServer>
       <handlers>
           <add name="*.ashx_*" path="*.ashx" verb="*" type="AjaxPro.AjaxHandlerFactory,AjaxPro.2" preCondition="integratedMode,runtimeVersionv2.0"/>
       </handlers>
     </system.webServer>
</location>

and it works normally on IIS 7 & Server 2008 & .Net Framework 4.0 & Classic Mode.
