I was working with Visual Studio 2005 and Crystal Report and the requirement is to export CR report to pdf file. Code used is kind of this: http://vb.net-informations.com/crystal-report/vb.net_crystal_report_export_pdf.htm When I use the complete report content it always error like this: Error in File D:\Users\username\AppData\Local\Temp\reportnameE9820B50-D2FE-48DE-9957-F759CD52BA74.rpt: Operation not yet implemented. I've checked and checked again but the error still appears. Then i found this forum: https://archive.sap.com/discussions/thread/3828300 Blank report or only hello word report would work fine. But my report is still error. From that forum too, I found that error could be because of window update that change font which doesn't fit. So we need to revert back. Font that is needed to re-install could be downloaded here! We could directly copy the files into C:\Windows\Fonts, but the best practice is to opend font file and click install button.
