In some rare cases, it might be necessary to completely remove Java from your system and re-install it.
Windows
Access the control panel via the Start Menu.
Click into Programs & Features or Add/Remove Programs or Programs - depending on your OS - and select to uninstall programs.
Once the list of programs has loaded (may take a while), scroll down to find Java.
It will look something like this: Java(TM) 6 Update 23
You may have multiple Java versions installed.
Uninstall it, then go to the Java homepage to download the latest version.
