Ghost Installer is an installation authoring system for Windows. Create single-file self-extracting setups for your applications. Using this version you can skin your program's installation. It also offers you a multilingual setup creation with support for more than 120 languages.
The Free Edition can be used for building installations with the variety of features. It has no visual tools for building the setup, and the installation is tuned manually via the XML code. Creating dialogs for Custom UI via XML is somewhat difficult, so the Free Edition provides the Standard UI plug-in, which is much more user friendly for XML-coders.
