NSIS

Purpose: NSIS is a tool for programmers to create Windows installers, including installers that can install, uninstall, change system settings, and extract files.
Scripting: Its installer-focused scripting language supports variables, functions, string manipulation, and custom installation logic.
Compression: NSIS includes ZLib, BZip2, and LZMA compression methods.
Installer interfaces: It includes classic and modern wizard interfaces and lets developers create custom pages and interfaces.
Languages: A single installer can support multiple interface languages, including right-to-left languages, and developers can create their own language files.
Extensions: NSIS supports plug-ins that can extend installer tasks and interfaces; plug-ins can be written in C, C++, Delphi, or another language.
Web and patching: Included plug-ins can download files from the internet, make internet connections, and patch existing files.
Builds: The compiler preprocessor can combine multiple projects into one installer, generate builds automatically, and create variants such as lite and full releases.
Integrity check: The feature list says installers can verify themselves using a CRC32 checksum.
License: The source code, plug-ins, documentation, examples, header files, and graphics are generally under the zlib/libpng license, with separate stated licenses for compression modules and exceptions noted on the license page.
Platform support: The compiler can be built for POSIX platforms such as Linux and BSD, while installers it generates run on Windows.
Support resources: The users manual links to a FAQ, wiki, and forum for questions and discussion.
