Adobe RoboHelp Server 8 is completely rewritten in Java and is much more stable and robust than previous versions. Installation is very simplified now.
One major difference from earlier versions is now RoboHelp Server 8 does not need IIS Server. Instead it uses Tomcat server.
You can download RoboHelp Server 8 trial version from http://www.adobe.com/downloads/
