What is the JRE?

The Java Runtime Environment (JRE) is a technology developed by Sun Microsystems that allows programs that are written in the Java programming language to run on different operating systems. The Galleon program can run on any operating system that has at least a 1.5 JRE.

Outdated Java

It is recommended that you use the latest 1.5 or 1.6 JRE. To determine the current version of your JRE installation, hit the Windows-key and R, enter cmd /k java -version and hit OK. If your version is not the latest, uninstall every Java you may find in Start->Settings->Control panel->Add/remove Programs (for Windows) Reboot your PC. Use a tool such as RegCleaner to clean the Windows registry after uninstalling old Java versions. Get the latest version of the JRE from Sun and install it on your system.
