Open Source Windows Installers

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.

Inno Setup is a tool to create installers for Microsoft Windows applications. innoextract allows to extract such installers under non-Windows systems without running the actual installer using Wine. NOTE: NEW VERSIONS WILL NOT BE UPLOADED TO SOURCEFORGE! Instead, use the official website at http://constexpr.org/innoextract/

The project is dedicated to create a graphical Win32 tool, which allows to install, run and administer the Chessbrain Peernode server (=the chessbrain client) on Win32 machines.

CrixerSoft InstallSphex Compiler is a professional Cross-Plattaform and Open Source for the development of Installers Developed in Lazarus, Supports Win32 only for now.

Installer Options is a small utility used to create option dialogs for use by NullSoft's NSIS installer application. NSIS is a very powerful install program, but lacks the ability to create dialog boxes to prompt the user for additional information. Please Note: This is an old project that was eventually integrated into NSIS distribution directly. The plug-in mechanism eventually changed, so this version of the code no longer works properly with NSIS. I have left the project online for archival purposes, but please use the bundled version instead.

***** IMPORTANT NOTICE ***** This NSIS modification has been merged with the official NSIS 2 project (http://nsis.sf.net).

XmlPreprocess is a tool that can be used to preprocess specially annotated XML files making property substitutions much like a code preprocessor. It is useful for deploying XML configuration files like .NET config files to a many environments.

NSIS is a professional tool for the development of Windows installers. Designed to be as small and flexible as possible, is therefore highly suitable for distribution. It's re-packaged to be portable so you can take it in your USB Drive, iPod, etc.
