NSIS is a professional open-source tool for the development of Windows installers.
Nullsoft Scriptable Install System in short NSIS is a professional open-source tool for the development of Windows installers. It is designed to be as small and flexible as possible and is therefore highly suitable for internet distribution.

An installer is not only the first experience of a user with your product, many software problems can also be solved by providing reliable installation tools. NSIS allows you to create stable, quick and user friendly installers that are capable of installing, uninstalling, setting system settings, extracting files and more. With the NSIS scripting language you can implement any custom logic you want.

The large collection of plug-ins, scripts and software in the Developer Center helps you to build full featured installers and provides a solution for almost every scenario.
