Have you created any user in phpmyadmin? If not, then create a new user with a password. Host should be 'localhost' (assuming you are doing this in your local pc using XAMPP / WAMP) and grant all permissions. Then use that user name and password as 'db-username' and 'db-password' at the time of installation. See if this error occurs again.
