Excelsior Installer
Excelsior Installer is a freeware development tool for creating software packages for Windows applications. It was created by a Russian company Excelsior LLC, known mostly for its Excelsior JET Java technology implementation.
The product is technically a fork of Excelsior JET deployment toolkit and inherits its UI. The first version of Excelsior Installer was published in the beginning of 2007. AbOUT a year later version 1.6 was released together with its commercial “sibling” named Excelsior Delivery, which offers an extended feature set.
The main intention of Excelsior Installer's developers is to simplify the creation of setup packages as much as possible. The product requires almost no learning effort and enables one to get a working setup package in a matter of minutes. The natural drawback of such approach is that feature set of the product is quite limited, supporting only the most basic installation scenario, which is also the most frequent though.
NSIS integration
Since version 1.8 Excelsior Installer features integration with NSIS (Nullsoft Scriptable Install System). The Packager is able to export a full set of scripts that may be immediately compiled with NSIS to produce a setup package functionally almost identical to the one created by Excelsior Installer itself. The script compilation and package test run are built into the Packager so the Excelsior Installer may act as a GUI front-end to NSIS, simplifying the creation of NSIS projects for novices. This feature also enables one to migrate with ease to a more powerful installation platform should Excelsior Installer's functionality become insufficient in the future.
