I'm using Unity 2017.1.3f1 (64-bit) on Windows. I'm not using any server files, I'm just trying to get the client to build but it won't.
I'm not using the pro version either, I don't know if that matters. We're clearly missing some kind of step in the instructions, as it seems like all of the Chinese people are like "Wow it works great!" while everybody else is like "wtf this doesn't work."
