Java Runtime Environment Error
 

I downloaded the Limewire:Basic Install file a couple of times and installed the program, but everytime I was at a certain point in the installation; where the java thing is installed, it fails. Then the installation continues but at the end a message pops up saying that Java has failed to install and that I need to get it from www.java.com.
However I can't get it from there due to some problems but I dont understand why this Java installation doesnt work in the first place. Please help!
