From the IPCC Express 3.1(3) Release notes:
If you create your own custom reports, Cisco recommends that you use Crystal Reports Developer Edition version 8.5. If you will integrate
custom reports with the Cisco CRA Historical Reporting system, you must use Crystal Reports Developer Edition version 8.5 to create the reports.
Currently we haved only tested with Crystal Reports 8.5 and hence the same is supported.
