Advanced Installer Professional 4.5 is a Windows Installer authoring tool which enables developers and system administrators to easily build reliable MSI packages. Advanced Installer runs on Windows 2000/XP, and the install packages it creates run on all Microsoft Windows 9x/ME/NT/2k/XP operating systems.

Windows Installer is a powerful, but very complex technology. Mastering it on your own takes months of hard work. That's where Advanced Installer comes to help. It creates a high level abstraction on top of the underlying technology. With a clean, simple user interface, each operation is logical and intuitive. Everything is done in the user interface, without complicated scripts to learn or arcane Datenbank tables to edit.

Advanced Installer is built on standard, open formats. The project files are saved as XML files for easy integration with source control systems. Advanced Installer is FREE for the simplest, most common usages. It also offers three additional licensing levels for more sophysticated needs: Professional, For Java and Enterprise.
