Crystal Report 2008 doesn't set page size when export to excel file

Question

Hi,
I am using Crystal Report 2008 Developer edition.
At Crystal report design time setting the below page setup:
Page Options -
   to A3(297X420 mm)
Orientation --- Landscape
and using the following code in .net (c#)
I am using below format options to export in excel in .net 2005
ReportDocument oReport = new ReportDocument();
oReport.FormatEngine.PrintOptions.PaperOrientation = PaperOrientation.Landscape;
oReport.FormatEngine.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.PaperA3;
if (aParamlist.ReportFormat == ReportFormatEnum.MicrosoftExcel)
ExcelFormatOptions excel = new ExcelFormatOptions();
excel.ExcelUseConstantColumnWidth = false;
// Use detail section one as a guideline to determine column width
excel.ExcelAreaGroupNumber = 1;
//excel.ExcelAreaType = AreaSectionKind.Detail;
excel.ExcelAreaType = AreaSectionKind.Detail;
// Prepare exporting options
ExportOptions export = oReport.ExportOptions;
export.FormatOptions = excel;
export.ExportFormatType = ExportFormatType.Excel;
oReport.Export();
when export to excel it doesn't set the Paper Size to  A3(297X420 mm).
Is there any way to set the paper size while export to excel or in other formats also????
Thanks & Regds,

Hi,
thanks for your email.
This is not happening in development environment.It is setting the paper size anf paper orientation properly.
this is happening in the production environment where only redist installation is done.
thanks
