WinbioOpensession returns E_ACCESSDENIED?

I am programming in VS2010 and Windows 7.

I am calling the WinBioOpenSession function from winbio.h

This is my code:

WINBIO_SESSION_HANDLE sessionHandle = NULL;

hr = WinBioOpenSession( 
            WINBIO_TYPE_FINGERPRINT,    
            WINBIO_POOL_SYSTEM,         
            WINBIO_FLAG_RAW,            
            NULL,                      
            0,                          
            WINBIO_DB_DEFAULT,          
            &sessionHandle             
            );

hr returns E_ACCESSDENIED return code?

How can I resolve this?

If you implement fingerprint methods in windows service running under LocalSystem account, you need to call WinBioAcquireFocus after WinBioOpenSession to focus current session.

The problem is that you didn't check the biometric logon option. Go to the Biometric option of the Control Panel and enable the biometric logon option.
