You must remove old Java files after running the script.
After the launch-update script runs, the Windows collector indicates successful update of the Java module, but the older version of Java may not have been removed. If the old version remains, you must manually remove the Java directory as described in this message:
Some files were left behind after the update of Java... Please manually remove directory 8.0u25 from the path 'C:\Program Files\APG\Java\Sun-JRE\8.0u25’
