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

  • Tiny overhead (less than 40kb)
  • Powerful scripting language
  • Unique compression options (zlib, bzip2, lzma)
  • Lots of plug-ins
  • Multiple language options

    Very useable, but with one major issue: installers cannot be used in any enterprise using Allow-Listing / Block-Listing Endpoint Management. If the Nullsoft dlls in your installer have a valid digital signature, than this comment is obsolete.

    I love NSIS and the nsis-mode in Emacs.

    Very good, could be much simpler to set up your setup script though.

    A free system for rapid development. It can be easily converted to msix. It helped me in two no profit projects :)
