Just to wrap up this thread...
The Client found over at playfh2 (and the one here, no doubt) also contains the dedicated server. After install, it's found in the root directory. If, like me, you are doing a LAN game and want to play co-op, you'll find there's a problem with the dedicated server. It needs a dll file. I got help over at FH2 Discord in their tech support section. File name was AIDLL_w32ded.dll. I think the devs planned have this fixed next time they release a version.
Thanks to LUckyone and Jan for all the help!
