Re : Sentinel LDK Licensing API was not found (400)

Hello Erik, 

Thanks for raising the concern.

This error usually comes when LDK Java interface fails to find the LDK Licensing API library (.DLL/.so).

Please put your vendor specific hasp_windows(_x64)_XXXXX.dll and HASPJava(_x64).dll in the JRE/bin folder. You can collect these files from below location after master key introduction.

C:\Users\<username>\Documents\Gemalto\Sentinel LDK 7.9\API\Runtime\Java

Please share the results upon trying.

Best Regards,

Parth Kaushik
