My operating system is Windows 8.1 (64 bit). Avast has been complaining that the Java installed is out of date. Occasionally, a popup comes on asking to update Java (it looks legit) and I press "ok". But it doesn't seem to do anything (repeating itself every day or so). Checking the list of installed programs in my control panel I found this,
I think it means that I have both 32 and 64bit versions of Java installed. How do I update these?
A generic search finds this question - How do I have Java auto-update for both 32-bit and 64-bit?
Which tells me that auto-update is unavailable for 64bit releases of Java. So, how do I do this manually? Should I uninstall the current Java runtime and then reinstall the new one, or can I just download the latest installer, run it and hope that it does an in-place install?
Some detailed step-by-step instructions meant for an idiot would be appreciated (if it's not asking for much).
