Hello ,

When generating a report with The CCR , I can't export it to MIcrosoft excel's format

OS : Microsoft 2008 r2 64 bit
SQL : Microsoft SQL server edition

an error has occured when crystal report generates the report.

error in File 62bfdb4b-527f-42d8-b46c-2f24371c2025 {0BC3F90A-5096-42AD-9ABB-05AB364BAD84}.rpt: Invalid export DLL or export format.
