How to set LoadRunner Agent as a service or process after installation

The LoadRunner Agent can be run both as a process and a service:

1. When running LoadRunner Agent as a process, it runs the ‘magentproc.exe’ from the <LoadRunner>\launch_service\bin folder. User needs to login to the machine in order to start this Agent.

2. When running LoadRunner Agent as a service, the service ‘magentservice’ runs automatically even if the user does not log in to the system. User can login to the machine and go to Administrative Tools -> Services -> ‘LoadRunner Agent’ to verify or change the authentication information.

After installing LoadRunner, user can switch the agent to be service / process anytime they want.


Agent options during Installation:
While installing LoadRunner, the following two options are provided for User Login settings:
1. When installed with option "Manual log into the Load Generator machine", LoadRunner agent is installed as process.

  1. I wish the machines I use (Win Server 2012 VMs) would conform – I can’t see how on earth the LR Agent Process gets started at login!

  2. Loadrunner Agent Standalone was the answer – it installed as a service on Windows 2012 R2 VM. Use the setup.exe which appears after the first step (unpacking) – that offers a choice of “Agent for Performance Centre = service” or “Agent for Loadrunner = as a Process”. Agent as a process is fine if the relevant login account is never auto-logged off.

  3. As per new policy of HP, Load Runner can be use with out having admin rights on the user. but do hp provisioned for changing load generator from service to process or vice versa.
    We are using standard user account for working with load runner and load generator, but while changing load generator from process to service getting access denied error.

    do we have any solution with which standard user can manage the configuration of load generator.

    I have found workaround in below url of HP load runner webhelp for issue but the mentioned file”” not found in complete system.

    On HP Web help workaround for the issues but the required file( subinacl.exe) in option not found on the system where complete Load runner or Load generator installed.
    URL :

    URL Content :
    When running the LoadRunner Agent as a service (magentservice.exe), and the Agent Configuration as administrator under UAC or a standard user: If you click the OK button and attempt to restart the HP Load Testing Agent Service, it issues the warning “Access is denied” .


    a.Run the Agent Configuration as administrator when UAC is off.

    b. If the current user is administrator, or a user having the appropriate permission to work with HP Load Testing Agent Services, go to Service Manager (services.msc), and manually start the LoadRunnerAgent service (and for Performance Center, the RemoteManagementAgent service).

    c.You can also run \bin\subinacl.exe as administrator to grant a user (user1 in examples below) full access permission of the target service. For example,
    For LoadRunner: subinacl.exe /service LoadRunnerAgent /grant=user1
    For Performance Center: subinacl.exe /service RemoteManagementAgent /grant=user1
