Ship, If your in Limewire, click on Help at the top of the page and then click on, About Limewire. You will see the Limewire version and also the Java version you have. If your not in Limewire you can go to Start > Control Panel > Add/Remove Programs and you will see it there. It will not show up on your desktop but maybe in your tool bar. Not sure about that. It doesnt show up either place for me. Not sure if that is an option
