My suggestions are to make sure yu have the most recent update of Java. Make sure you're not attempting to install from Classic mode (in fact, quite classic.) Quit all other running applications. Launching either from a double-click in the UI, or by using the absolute path (/user/Desktop/LimeWire.bin or otherwise.) And also see these points: Repair Permissions & Safe Mode Failing all of those, try the english/international installer.
