If users see this message when trying to run a Crystal Report over the web:
CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException: Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack. at CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.Open(Object&
DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.Open(Object& DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened() --- End of inner exception stack trace --- at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened() at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename, OpenReportMethod openMethod, Int16 parentJob) at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename) at
site.AspNetForms.ReportViewer.Page_Load(Object sender, EventArgs e)
The key portion of the warning is: "A document processed by the JRC engine cannot be opened in the C++ stack."
It means it cannot locate the required file. They should check the Reports folder in webManEx for the file listed below the "Run Report" button in the report manager.
