Welcome to the Community!
I don’t see any error on your screenshot. Can you tell us more?
Welcome to the uipath community.
Could you please tell us more details about the issue.
Seems that you have already some robot configured for this machine.
so what should I do for that
Please check all robots and remove the one attached to this machine/computer and the you should be able to configure new robot for it.
please describe with the image
If you don’t have such robot then it might be that you are trying to name robot identically like the machine. Try different names.
