The older versions of LW older than 4.3 should use Program Add/Delete Control panel. See:
Fixes for Limewire BUT instead of choosing repair you choose Remove! If you had the international/multilingual installed version then you should find an uninstaller under the Start>Programs>LW menu or else within the LW folder. If this doesn't solve it then use:
Windows Installer CleanUp Utility (click on link)
Then update your Java!!! Then update your LW by downlding the installer & saving to your HDD. Then install it.
