Limewire downloads successfully on my computer but when I go to run it it says there was a problem during installation and is unable to run. Why does it say it is downloaded successfully if it isn't and how do I get it to install properly??

Sorry for very late reply, somehow your post was missed. If your problem was not fixed, try this: http://www.gnutellaforums.com/355685-post13.html and also delete your LW preferences folder whilst keeping a backup of the downloads.dat file.
