NJStar is not native Linux application, so it can not run on Linux directly. Some of our users report that they can use NJStar WP on Linux with the Help of a product called Crossover for Linux, which enable you to run lots of windows Applications on Linux. You can download a free trial version 'Crossover for Linux' here, http://www.codeweavers.com/products/cxlinux/

There is also an Open Source alternative for Crossover called WINE. You can download WINE to install on all distributions of Linux, such as Redhat Linux, Ubuntu Linux, openSUSE Linux,  Mandriva Linux , Slackware Linux, Debian Linux, etc.

After you have Crossover or WINE installed on Linux, you can then download and install NJStar WP within CrossOver or WINE.
