I tried the quick fix in the other post using BFU but it didn't work I still got the error...

Your first post's not clear. Are you trying to install LW? Or have you uninstalled it, & now the startup error is popping up all the time?
The BFU fix is for people infected with a worm & whose LW pops up all the time & won't stay closed.

I'm trying to instal, I just got my internet back, and when I whent to open limewire I got that message. so I downloaded the installer and try'd installing it again. i then found the post with BFU and I tried that, when I reinstalled it still gave me that error everytime I open limewire.

That error comes up when I try to open the installed limewire.

First of all install Java. Use the JRE offline installer here. Remove your current Java version before you install the new one.

Once that's done, delete LW's preferences folder. See point 3 here. If you've used much older versions of LW, you could have a folder in point 2's location as well...so check both.
Fixes for LimeWire

Last of all, reinstall LW & make sure to use the offline installer (not the recommended one).
