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)
