Question

• What is the hasp_rt.exe ? what is it for?
• When exactly is it required?
• WHAT IS THE POINT OF HAVING HASP_RT.EXE ? our tests over a year shows that the dongle works without hasp_rt.exe. Can we skip it, if yes what are the consequences?

Answer

• What is the hasp_rt.exe? what is it for?

hasp_rt.exe is the External License Manager for the LDK 7.x or newer protected applications. It is mainly used to handle accessing of local Driverless keys (HL or SL). It will also be able to close any active sessions in case of an application crash.

• When exactly is it required ?

hasp_rt.exe is not technically required, as you could use either the Admin License Manager (hasplms.exe, included with drivers), or the Integrated License Manager (included internally inside of the LDK protected application).

• WHAT IS THE POINT OF HAVING HASP_RT.EXE ? our tests over a year shows that the dongle works without hasp_rt.exe. Can we skip it, if yes what are the consequences?<

Most times this file is needed if your Enveloped application may crash at exiting of the application. If your protected application is able to work fine without using this hasp_rt.exe, then that is fine too. Consequences for not including that hasp_rt.exe are mainly that you are limited to using either the Admin License Manager or the Internal License Manager.
