Nullsoft Scriptable Install System 2.0

An installer is the first experience of a user with your application. Slow or unsuccesful software installations are the most irritating computer problems. A quick and user friendly installer is therefore an essential part of your software product.

NSIS can create installers that are capable of installing, uninstalling, setting system settings, extracting files, etc. Because NSIS is based on script files, creating both simple or advanced installers is possible. From a small installer that extracts a few files to an installer that handles the upgrading, file patching or downloading for multiple versions. You can also integrate parts of your software configuration. The script language is supports variables, functions, string manipulation, just like a normal programming language - but designed for the creation of installers.
