Most of the CellSpark products are packaged as a "JAR" file which will run on a Windows PC much like a Windows ".exe" file does, by double clicking it. Windows users will first need to install Sun's Java 2 on their Windows PC unless your PC supplier has pre-installed Java 2 before delivery.
Java 2 is a free download from SUN Microsystems. It's recommended you install the smaller "JRE" unless you are writing code. Click on the latest J2SE version and you will see the "JRE" download listed. Desktop Java can also be installed from Java.com. Note that some products require at least Java 1.5 to run
There is a Mac Java 2 runtime available
at Apple's Java page if you don't already have it.
