Need to allow Excel Export with 10.1.16.615 version on FIPs enbled

Hi Team,

I had tried with the provided post as below with DocumentFormat.openXML.dll verison (2.5) but not working .

please help to resolve this ASAP.

Based on what you described and the ticket info, I am assuming that you are getting this error when you render a report in the Excel 97-2003 (XLS) format. Is that correct?

Unfortunately, this is a known limitation of the Excel 97-2003 rendering, and exporting a report to XLS in FIPS-enabled environments will fail. Considering this, I suggest choosing one of the following options for exporting reports to Excel:

• Exporting the report to the newer XLSX format. (See exporting in XLSX)
• Disabling FIPS.

If choose the first option, you can disable the older Excel rendering format so that it is not available as an option when the report is displayed in a report viewer. For example, the following code can be put into the web.config/app.config of the project:

<configuration>

  <configSections>
    <section
        name="Telerik.Reporting"
        type="Telerik.Reporting.Configuration.ReportingConfigurationSection, Telerik.Reporting"
        allowLocation="true"
        allowDefinition="Everywhere"/>
  </configSections>

    ...

  <Telerik.Reporting>
    <extensions>
      <render>
        <extension name="XLS" visible="false">
        </extension>
      </render>
    </extensions>
  </Telerik.Reporting>

   ...

</configuration>

I hope this helps, please let me know if you have any additional questions. Thank you for trying Telerik Reporting!
