PatchMyPC Free 3.0.2.3 is confused with installed version (See Attached Screen Shot)
The problem with Java is that it won't uninstall its previous versions. They do this because some old applications require specific (=older) Java versions so if you only have the latest one, they might not work. That's rare though. Try closing your browser (always do that while installing/uninstalling Java), uninstall all Java versions then install just the latest one.
