Also i want to set automatically start the robot when system start in Client machines .How?

If you are installing at scale, then it’s probably best to use the command line features. See Robot - Installing the Robot

And the Robot is installed as Windows Service, so you can configure to start when the system is started.

A Robot is installed as a Windows Service by default. As a result, the Robot can open Windows sessions (interactive or non-interactive), under the Local System account, and has all the rights of a Windows service.
