Can't add user via command line

I am trying to add a user via the command line through a virtual pc I added with VMWare. I'm running windows 10, and unable to add because this is what I get when I open CMD: I can't go beyond this point, I keep getting error messages. Any help would be deeply appreciated. Thank you, Tina

Have you tried doing this via an elevated command prompt? Right click on the start button icon and select Command Prompt (Admin)

Thank you, but I figured it out. Took me a little bit, all I had to do was signed on as administrator.
