this is where i went and it worked. i downloaded the install wizard and it brought up a list of programs. i clicked on limewire and uninstall and it was gone immediately. after literally months of trying to get this program off something finally worked. if you are getting an error though doing it this way i don't know what will help.
hope this helps you as well as it did me.
