During the installation of LoadRunner if you select “Allow virtual users to run on this machine without user login”, the LoadRunner agent will run as a Windows system service called “LoadRunner Agent Service”.
If you choose “Manually log in to the Load Generator “, the LoadRunner agent will be run as a process named magentproc.exe. This means you need to start the LoadRunner agent manually each time you reboot the PC/server or you need to put the LoadRunner agent process into a windows startup group.
Some vUser types will only run if the agent is running as a service (GUI, SAP, Citrix etc.). This is because they need to run in a user context.
After installation, to switch from running the LoadRunner agent as a service to running as a process:
Add this shortcut to the startup folder – “C:\Program Files (x86)\HP\LoadRunner\LAUNCH_SERVICE\bin\magentproc.exe”
After installation, to switch from running the LoadRunner agent as a process to running as a service:
Remove the LoadRunner Agent Process from the Startup folder
N.B. You need admin rights to do this. The magentservice.exe file is in the C:\Program Files (x86)\HP\LoadRunner\bin or C:\Program Files\HP\LoadRunner\bin folder.
