The PortableApps.com Launcher (also known as PAL) is used to make applications portable by handling path redirection, environment variable changes, file and directory movement, configuration file path updates and similar changes, as configured.[10] The PortableApps.com Launcher allows software to be made portable without the need to write custom code or make changes to the base application. While some of the software packages released on PortableApps.com currently still contain their own custom launchers, the PortableApps.com Launcher is used in all new apps released.[11] The installers are made with Nullsoft Scriptable Install System.
