Since ACC update 1.5.8 the server is a standalone item in the steam library so the new correct path would be "...\Assetto Corsa Competizione Dedicated Server\server"
Great Job Martin, I wanted to make you a suggestion and that is if you could update the multi-language version, or at least in Spanish, it would be easier for me and for many Spanish-speaking people.
Thanks and great work
Great job on this. Makes hosting private sessions with friends painless. Probably something that should have been included with the game to begin with.
