I checked briefly through your code and the problem seemed to be that diskDestination.
I'm not sure since I'm not a pro. In my point of view, HTML is not only a file, it contains many objects and they're in a folder. Then when you creating a file but not a file and a folder, things might not working your way.

        Try
            Dim selectedReport As New ReportClass
            Dim CrFormatTypeOptions As New HTMLFormatOptions
            CrFormatTypeOptions.HTMLBaseFolderName = "d:\test"
            CrFormatTypeOptions.HTMLFileName = "htmlformat.htm"
            Dim CrExportOptions As ExportOptions
            CrExportOptions = myReportDocument.ExportOptions
            With CrExportOptions
                .ExportFormatType = ExportFormatType.HTML40
                .FormatOptions = CrFormatTypeOptions
            End With
            myReportDocument.Export()
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
