Hi, It seems the Server Edition doesn't work on 2012 R2.
I have been through the process of turning off firewalls and antivirus and can't make it work. It extremely frustrating. I have Server Edition working from one of our Client machines with no issue.
It appears to install onto the server ok but no clients can find the library on the server.
Please confirm if it actually works on this version of windows server and what else needs to be done to make it work.
