Remove your java, then step back to this version: Archive: Download Java 2 Platform Standard Edition (J2SE) 5.0 Update 11 & ONLY choose the OFFLINE Java JRE version to download & then install. Installing java over the internet often comes up with errors & is a common problem with corrupt installations. If still problems, then get the OFFLINE installer for LW then install it. It will uninstall the other version of LW during installation.
