"Error loading RadChart Image" on IIS7

Question

I'm using a Telerik RadChart control on my ASP.NET web application.

This works fine when running on localhost, but now the application has been deployed to IIS7 and the following error appears:

Why is this? And how can I resolve the issue?

I've seen on some forum posts that the solution is to add the following into <system.webServer> in the web.config:

<add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode,runtimeVersionv2.0"/>

However, I have already done this, and the error is still appearing.

in web.config file... add the following:-

 <system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true"/>
    <handlers>
      <add name="ChartImage.axd_*" path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4" preCondition="integratedMode" />
      <add name="Telerik.Web.UI.SpellCheckHandler.axd_*" path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4" preCondition="integratedMode" />
      <add name="Telerik.Web.UI.DialogHandler.aspx_*" path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4" preCondition="integratedMode" />
      <add name="Telerik.RadUploadProgressHandler.ashx_*" path="Telerik.RadUploadProgressHandler.ashx" verb="*" type="Telerik.Web.UI.Upload.RadUploadProgressHandler, Telerik.Web.UI" preCondition="integratedMode" />
      <add name="Telerik.Web.UI.WebResource.axd_*" path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI"  preCondition="integratedMode" />
    </handlers>
