I have a cancelled install of JDK1.6 (64b), and I can't uninstalled later. So I re-installed it and un-installed it. It's ok now. The only issue if that I can't open Java Control Panel since then.
I have JDK1.7 installed now, still when I click Java Contral Panel icon, nothing happens. I tried start it from the jre/bin dir, still not work.
Anyone have any suggestions/ideas would be much appreciated!
