Can we launch NeoLoad GUI from command prompt? Is yes, Can you please let me know the command.
How do we activate NeoLoad controller license on CentOS?
You could start the NeoLoadGUI but it means that you have a display or you can export your display to a remote machine.
Otherwise if you follow the procedure described here you should be able to activate your license without any UI.
Do you mean launch as in run the test? you can use the NeoloadCmd and the necessary arguments
