WiX is a free and open-source software toolset for creating Windows Installer packages, which is used for the installation and maintenance of software on Microsoft Windows operating systems. It is developed by Outercurve Foundation, a non-profit organization. WiX consists of a set of tools that allow developers to create Windows installer packages from XML source code. It uses a declarative XML syntax to define the structure of the installation packages and a set of standard tools to build and maintain them. WiX includes a graphical user interface to create MSI packages, as well as a command line interface, which can be used for automation and scripting. WiX also provides support for COM and Windows Registry integration, and includes support for creating MSI packages for services, web applications, and virtual applications. WiX also includes a command-line tool, Heat, which can be used to generate WiX source code from existing Windows Installer packages, as well as other file types.
