I was surprised I did not have to re-edit any configuration file or fix file permissions or anything. It worked perfectly from the first trial. However, in case you run into trouble, an explanation on solving your installation problems is in the documentation. Documentation X-ISP comes with a large amount of technical documentation discussing implementation issues, security, architecture, and the interaction between the different components. It also has a good help facility that guides the user through setting up X-ISP step by step.
Help is also available on-line from the main window.
