I had installed limewire, I think 4.13, and it worked fine, but I unistalled it. Then, I wanted it back, and I reinstalled, and it worked fine again. Then, came the newer limewire, and I installed it, and I think it worked fine as well. Finally though, I tried installing the newest limewire, with the updates and what ever, and it goes through all of it, untill it gets to about the middle of the installation and then it said there was an error, and now it won't work. So I tried unistalling the installed files, and installing it over and over again, and it did the same thing every time. And when I try to bring up limewire, it just gives me an error and a code. Can someone please help me?!

What error & code are you seeing??

First thing to try is deleting LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used much older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

Have you updated your Java since LW was working? What version of Java are you using?

System Details

When I try to use limewire, it says "One or more files may be invalid." And during the installation, it said that there was somthing wrong with the installation, but I can't fix it. Here's the code:

Update your Java to this version. Download the JRE offline installer & remove any other Java versions before you install this one.
Archive: Download Java 2 Platform Standard Edition (J2SE) 5.0 Update 11

Next, delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).

Last of all, reinstall LW. If you're going to reinstall the latest version of LW (4.14.8), make sure to use the offline installer. When you click to download LW & the dialog box pops up, cancel it. You'll see the option to download the offline installer
