    Use Google and search for this KBA:

    2105311 - ExportToStream throws exception in SP 12 in Crystal Reports for Visual Studio

    Not supported, use

    System.IO.Stream stream = reportDocument.ExportToStream (CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)

    Use Fiddler and/or ProcessMonitor and or Hit F12 in Browsers and see what is generating the error.

    Dim report As CrystalDecisions.CrystalReports.Engine.ReportDocument

    Dim oStream As System.IO.MemoryStream

    report = New CrystalDecisions.CrystalReports.Engine.ReportDocument()

    report.FileName = "MyReport.rpt"

    report.SetDataSource(TableData)

    report.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.PaperLetter

    oStream = report.ExportToStream (CrystalDecisions.Shared.ExportFormatType.WordForWindows)

    Above line generates error. This line works fine on visual studio 2013 and windows 7 pc.
