Hi MGrassman,

Most likely you are referencing the XPS rendering extension somewhere in your code or in your web.config file. Thus, you need to have the Telerik.Reporting.XamlRendering assembly present in the bin folder of your web site/app. More information about deploying Telerik Reporting is available in the respective help article: Deploying Applications using Telerik Reporting.

Kind regards,
Steve

Hi,

I do get exactly the same error as described above using Q1 2012 (6.0.12.215).
The help site you've mentioned is no longer available.

I've added the following Assemblies to the server

Telerik.Reporting
Telerik.Reporting.Adomd
Telerik.Reporting.DatabaseSession
Telerik.Reporting.OpenXmlRendering
Telerik.Reporting.Service
Telerik.Reporting.XpsRendering


Withing the web.xml the following render extensions are enabled

<Telerik.Reporting>
    <Extensions>
      <Render>
        <Extension name="IMAGE" visible="true"/>
        <Extension name="PDF" visible="true"/>
        <Extension name="CSV" visible="false"/>
        <Extension name="XLS" visible="false"/>
        <Extension name="XLSX" visible="false"/>
        <Extension name="RTF" visible="false"/>
        <Extension name="HTML" visible="false"/>
        <Extension name="MHTML" visible="false"/>
        <Extension name="XPS" visible="false"/>
        <Extension name="DOCX" visible="false"/>
        <Extension name="PPTX" visible="true"/>
      </Render>
    </Extensions>
  </Telerik.Reporting>


I'm totally lost because until the redeployment today everything worked just perfectly and I did not change anything concerning the configuration.

By the way. We are using the Silverlight ReportViewer component of Q1 2012

Kind regards
Sebastian

Solved by myself.

Seems I've messed around with the DLLs.

Copying the DocumentFormat.OpenXML.dll into the /bin directory worked for me.
