media encoder on network server without license

hi, i have a windows server that i would like to use as a network render farm with media encoder for after effects and premiere.  the problem is that i currently have adobe cc license installed on a laptop and desktop pc.  i read that there is an app called aerender, but i wasn't able to figure out how to get it to work.  is it possible to do this without a license, or can i purchase a 3rd license?
