Have a look in Add and Remove, if you have old Java utilites present uninstall them manually or download and run JavaRa.exe to do it for you.
The latest Java Runtime Environment can be found here.
You do need to keep Java up to date as old versions are vulnerable to your system and should always be removed before installing the newest version.
