Errors on Windows2003 with Web Application Framework 4.0 + CR_VS2010

Question

Hi,
I have a new scenario about this problem e I would like get some opinions to solve this.
We have a web Application (Asp.net + vb.net) wrote in VS 2010 using CR_VS 2010 running with Framework target 4.0.
In Windows 2008 32bits or 64bits (IIS 7.0) the application works fine with Crystal Reports.
In Windows 2003 32 bits or 64 bits (IIS6.0) some resources of Crystal Reports VS2010 doesn't work like in Win2k8, we have a page that export a report to disk using data set and always receive the message:
".. Could not load file or assembly 'file:///C:Program Files\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified: C:\Program Files\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll"
The same application is useful on Windows 2008, we follow the instructions identified by KB 1540637, 1525432 and 1217986 but the problem was not solve.
Another thing that was very strange in this environment ((Windows 2003) is:
We have a console application that use CR_VS2010 and here the Crystal Reports works perfectly with this lines in application.config:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0"/>
</startup>
Is important remember that Web.config of our application already has the configuration above and don't have any reference to another cystal reports (only the version 13 (cr vs2010)).
Can you help us ?
Thank you and sorry for the bad english.

Hi All,
Thanks for waiting. I have the info now...
It is fixed in CR 2008 as well.
This should work also for CR for VS 2010 now, SP is not required, add this key to your PC's:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Crystal Reports\DesignerOptions]
"DealWithMinimalMarginsWhenPrinting"="0"
             Key=0  =>  minimal margins
             Key=1 or delete key  =>  large margins
As well here the sample code and note the PrintToPrinter does NOT read this key, you must use RAS:
For Winform Viewer, it will not impacted this fix... in CR.Net SDK, if user used reportdocument print function like:
reportDocument.PrintOptions.DissociatePageSizeAndPrinterPaperSize = true;
reportDocument.PrintToPrinter(1, true, 1, 1);
or they tried to print via CrystalReport Winform Viewer
            reportDocument.PrintOptions.DissociatePageSizeAndPrinterPaperSize = true;
            this.crystalReportViewer1.ReportSource = reportDocument;
            this.crystalReportViewer1.PrintReport();
Even by setting the following registry key to u201C0u201D, the print out page will be large margin.
[HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 12.0\Crystal Reports\DesignerOptions]
"DealWithMinimalMarginsWhenPrinting"="0"
However if you using RAS.Net SDK to print like following code, it will be affected by the fix:
            ReportDocument reportDocument = new ReportDocument();
            reportDocument.Load(@"C:\Users\Administrator\Documents\Visual Studio 2008\Projects\CrystalReportsApplication1\CrystalReportsApplication1\CrystalReport1.rpt");
            reportDocument.PrintOptions.DissociatePageSizeAndPrinterPaperSize = true; // Please note that, this code is does nothing. The only impacting to print result is the registry key.
            CrystalDecisions.ReportAppServer.Controllers.PrintReportOptions printReportOptions = new CrystalDecisions.ReportAppServer.Controllers.PrintReportOptions();
            printReportOptions.AddPrinterPageRange(1, 1);
            printReportOptions.PaperSize = CrystalDecisions.ReportAppServer.ReportDefModel.CrPaperSizeEnum.crPaperSizePaperA4;
            printReportOptions.PrinterName = @"\\CNPVGL002\CN64_BW";
            CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rptClientDoc = reportDocument.ReportClientDocument;
            rptClientDoc.PrintOutputController.PrintReport(printReportOptions);
Thank you
