Configure Network button is greyed out during install

I am installing an evaluation copy of RHEL 6.4 and after putting in the computer name the "Configure Network" button was greyed out. I have not installed RHEL in quite a while and would rather have the network setup be guided, versus manual if possible. Additionally, I found that the Network Manager daemon was not installed on this package; I could not find where to get that installed.

Is the fact that the Configure Network button is greyed out a sign of a larger issue?
