Hi,
What happens when you type your .local address in the hostname box
during the installation? I haven't tested the installer with that type
of hostname, but it should be ok. It does not have to be a
www.example.com domain -- all you need is a hostname or IP that all
clients (and the sever) on your network can use to access the server.
If you want to change the hostname after installation you can do so in
the host config in the admin folder.
