共享主机上的Report Viewer配置错误

Question

I have developed ASP.NET Application which requires ReportViewer for functionality. My Site is working perfectly well on localhost. I was asked by my shared hosting provider to upgrade the ReportViewer version from 11 to 12 which I did and it is working fine on local host. But on shared hosting space I am getting below error: ReportViewer Configuration Error

The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add to the system.web/httpHandlers section of the web.config file, or add to the system.webServer/handlers section for Internet Information Services 7 or later.

My Web.Config file

<configuration>
  <system.web>
    <customErrors mode="Off"/>
    <httpHandlers>
      <!--<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=000000000000" validate="false"/>-->

  </system.webServer>
  <appSettings>
    <add key="ValidationSettings:UnobtrusiveValidationMode" value="None"/>
  </appSettings>
</configuration>

I have also added all the 3 DLL files in BIN Folder

Can anyone please guide me where I am wrong?

Thanks in advance
