title: ASP.NET + C# -- Exporting Crystal Report to PDF -- Error + Upgrade Needed?
body: <p>I'm maintaining a multi-project solution in ASP.NET + C#. We've decided to upgrade to .NET Framework 3.5 and ASP.NET 2.0. One of the last issues with the upgrade is with Crystal Reports.</p>
  
  <p>I'm getting the following error:</p>
  
  <blockquote>
    <p>Method
    'ISCREditableRTFExportFormatOptions_reserved5'
    on type
    'CrystalDecisions.ReportAppServer.ReportDefModel.EditableRTFExportFormatOptionsClass'
    from assembly
    'CrystalDecisions.ReportAppServer.ReportDefModel,
    Version=11.0.3300.0, Culture=neutral,
    PublicKeyToken=692fbea5521e1304' is
    overriding a method that has been
    overridden.</p>

  <p>They suggest that I upgrade crystal reports to version R2.</p>
  
  <p>What exactly does this mean? Do I just need to package different DLL's in my bin folders? Or do I need to uninstall and install the new version of Crystal Reports software on the test &amp; production servers?</p>
  
  <p>Thanks in advance for your time.</p>
