Hey, I found a reply on another thread that helped me. This was it:
naturally, make sure you have java installed. If it is, find the file javaw.exe on your computer.
Make yourself a shortcut that says
"pathtoyourjavawfile\javaw" -classpath RunLime.jar RunLime
next to "start in" make sure it has the path of the directory where LimeWire.jar is.
That should be all you need to do.

It took me a bit to play around with it, but now when I double click on the javaw shortcut on my desktop, it opens up Limewire! Hope this helps.
( In the place where it says pathtoyourjavafile, just leave the path that's in there and only add the -classpath part at the end)
