Portable Nullsoft Scriptable Install System

NSIS Portable is the no-installation version of the NSIS (Nullsoft Scriptable Install System). Its purpose is to make full-blown Windows installers, complete with the ability to remove the data added to the system, organizing the settings or extracting files and performing other necessary routines.

This edition does not run you through a proper installation routine but instead guides you through the steps necessary for extracting the files wrapped in the executable.

Looks are simple and the main application window provides access to additional resources that can be used, such as plug-ins or documentation data.

The compiler offers the possibility to create an installer from NSI scripts which can be easily loaded by dragging and dropping it straight into the MakeNSISW window. There are multiple compressors to pick from, the default being the one defined in the script.

At the end of the process users have the chance to test the installer in order to make sure that the operation concluded without a glitch.

Alternatively, the program can create an installer starting from a ZIP file. Thee aren’t too many options available, but you get to enter the name of the installer, choose between a modern or a classic interface as well as define the default path for extracting the data.

To make things easier there are predefined paths at your disposal. These can be anything from the temporary folder, the start menu, the desktop or the Program Files area. Again, there is the possibility to select a compressor and you can test the output file.

NSIS Portable is a powerful installer creator that is easy to use at a first glance but provides a hefty list of functions and sufficient documentation to allow customization of the resulting installers.
