Hello Mauricio,

This is a generic .NET error that is not directly related to Telerik Reporting. Judging by the stack trace from the screenshot, the problem seems to be related to the web viewer http handler registration. In IIS7, the handler of the viewer should be registered in the <system.webServer><handlers> section like so:

<system.webServer>
    <handlers>
      <add name="Telerik.ReportViewer.axd_*" path="Telerik.ReportViewer.axd" verb="*" type="Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=5.3.11.1116, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" preCondition="integratedMode,runtimeVersionv2.0"/>
     ......
    </handlers>
....

This information is available in the How to: Add report viewer to a web page help article.

Kind regards,
Steve

Hello mauricio,

Let's continue the discussion in the other thread you've opened. We kindly ask you to use just one support channel to contact us. Posting the same questions numerous times slows down our response time because we will need to review and address two threads instead of one. Threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread.

Thank you for your understanding.

Kind regards,
