LDK 7.0 Integrated License Manager

On Envelope with 7.0, we get hasp_rt.exe along with the protected application in the same directory. hasp_rt.exe is the external license manager.


If we remove hasp_rt.exe from the protected application directory, the protected application still run. Here comes the role of integrated license manager.


Integrated license manager is included in all applications that are protected with Sentinel LDK Envelope (7.0).


 In LDK 7.0 the license manager is searched as per the below hierarchy:

  1. Admin license manager: The Run-time Environment  includes device drivers and Sentinel Admin Control Center, which is the interface for the License Manager. It manages all sentinel keys except for SL User Mode keys.
  2. External license manager: External License Manager is contained in the file hasp_rt.exe. This file is placed in the same directory as the protected application. It is available for windows only.
  3. Integrated license manager: Integrated License Manager is available in all applications that are protected with Sentinel LDK Envelope (7.0). This is also available in windows only.
