NSIS (Nullsoft Scriptable Install System) is a professional open
source system to create Windows installers. It is designed to be as
small and flexible as possible and is therefore very suitable for
internet distribution.
Being a user's first experience with your product, a stable and
reliable installer is an important component of succesful software. With
NSIS you can create such installers that are capable of doing
everything that is needed to setup your software.
NSIS is script-based and allows you to create the logic to handle
even the most complex installation tasks. Many plug-ins and scripts are
already available: you can create web installers, communicate with
Windows and other software components, install or update shared
components and more.
Features
NSIS can create
Windows installers that are capable of installing, uninstalling, setting
system settings, extracting files, etc. Because NSIS is based on script
files, you can create both simple and advanced installers.
Small overhead size
NSIS is created to be small, fast and efficient. While other
installers often add hundreds of kilobytes or several megabytes to your
installer data, a full-featured NSIS installer has an overhead of only
34 KB.
Compatible with all major Windows versions
You can create a single installer that is compatible with Windows 95,
Windows 98, Windows ME, Windows NT, Windows 2000, Windows XP, Windows
Server 2003, Windows Vista, Windows Sever 2008 and Windows 7.
Unique compression methods
You can choose between three different integrated compression methods
(ZLib, BZip2, LZMA). The new LZMA compression gives better results than
any other common compression method. You don't have to use large
self-extracting archive modules or other applications. The compression
support is included in the 34 KB overhead.
Script based
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 and more.
For standard installers or as a starting point for more complex ones, you can use one of the available script generation tools.
Multiple languages in one installer
One installer can support multiple interface languages. More than 40
translations are already included, but you can also create your own
language files. RTL (right-to-left) languages such as Arabic and Hebrew
are fully supported.
Many features and checks for the target system
The script language provides commands you can use on the target
system, from simple features like folder creation and registry editing
to text/binary file modification, modification of environment variables
and system reboots. Using provided plug-ins, you can even use Windows
API.
Custom dialogs and interfaces
You can create custom wizard pages to get user input or integrate
configuration options. NSIS includes a classic and modern wizard
interface, but it is even possible to create your own custom interface.
Plug-in system
NSIS can be extended with plug-ins that can communicate with the
installer. They can be written in C, C++, Delphi or another language and
can be used to perform installation tasks or extend the installer
interface. You can use the plug-in with a single line of script code.
Plug-ins can also be compressed like other installation data and will
only be included when you are using the provided features.
Support for web installation, file patching
The NSIS distribution includes a set of plug-ins that allow you to
download files from the internet, make internet connections, patch
existing files and more.
Project integration, different releases and automatic builds
The NSIS compiler features a powerful preprocessor. This allows you
to easily integrate multiple projects into a single installer or
automatically generate installer builds. You can also generate different
releases such as lite and full versions.
Easy and human readable file formats
The NSIS script format and the format used for interface dialogs are
easy, documented and humanly readable, so you can edit your files with
your favorite editor. This also makes automatic script generation
possible.
Portable Compiler
The NSIS compiler can be compiled for POSIX platforms like Linux and
*BSD. Generated installer will still run on Windows only, but this way
they can be generated without Windows or WINE.
