CR 11.5 RDC SetlicenseKeyCode

Hi

I am using craxddrt.dll for design at run time. I want to set license at run time through code using vc++.

I have the CR 11.5 Developer Version (30 days Trial Version)

IReportPtr m_crReport;

m_crReport->Application->SetLicenseKeyCode("xxxxxxxx");

but this is not working....

When i debug then error through is "m_crReport->Application CXX0063: Error: overloaded operator -> not supported"

Thanks.
