problem with 180 evaluation version

[sap1958]

Im attempting to install sql server 2008 evaluation. Once I get pass instance configuration I see Service Accounts. I click ok and I get validation errors with a message asking me for valid account and password for the following:
SQL Server Agent
SQL Server Database Database Engine
SQL Analysis Service
SQL Reporting Services
SQL Integration Services. I see NT Authority and this one passed ok. THe other have no acount information. Is that why I cannot get passed this area and install? How can I solves this problem

You will need to provide an account and password to get started.
