Make installers for the applications that you create. Supports third-party plugins that extend its functionality aside creating web installers.

NSIS is an open source system that enables you to create Windows installers. Unlike other systems that can only generate installers based on a list of files and registry keys, NSIS has a powerful scripting language. This script language is designed for installers and has commands that help you to perform many installation tasks. You can easily add custom logic and handle different upgrades, version checks, etc.
