Try enabling new user registration in Global settings - users
and
Publish the k2 users module either on a page you create or in a login position of your template and it will present a Create New Account option

Thank you William

I follow your steps but i didn't find (enabling new user registration in Global settings - users) and when i create new module i just found (K2 user), i think supposed there is (K2 registration form), I need to create K2 registration form for allow new user register and add new K2 item (i created K2 user group with some permissions and i need to assign it to K2 registration form)

Thank you in advance

Goto Joomla Global Settings, Look to the bottom left "Users"
