Hi, have you installed the server (Zentity.Installer.Server.msi) on your
own computer first? The client connects to some web services, which have to run either on your computer or on another one (which is, of course, accessible to you through the network). If you haven't installed Zentity your local computer, then just
change "localhost" to the name of that machine e.g. "zentityserver" or whatever it's NetBIOS/DNS name might be.
