The only thing I've been seeing with errors lately is anything related to the loginserver, which yes if you're looking to login from another PC on the network you will need to use the address that it resides on the network with and not 127.0.0.1 because that is only a locally significant address. With that there is some basic networking to be aware of.
Otherwise it looks like the new installer is ready to go from what I can see.
