How do I install the IENJINIA Devkit?
First you must unzip the file you downloaded (this is done automatically on Mac OS X when the download finishes). On Windows you can use a program like WinZip. On Linux you can use the unzip command in a shell window. The IENJINIA Devkit is a Java program so you also need to have Java installed in your machine. You must have Java version 1.4.2. On most modern Windows computers Java is already preinstalled. If it isn’t you can download it here. On Mac OS X you always have Java. If you don’t have the correct version (1.4.2) click on the apple at the left of your menu bar and select Software Update… to install the latest version. On Linux you can download Java from here.
