FredMcD:

Java is already to set to 'Ask' but the issue remains.

Can you test my issue by going to the Java website using Firefox and checking for the latest version?

The Java website is not scanning for the latest version of its own software but I can 'check' the latest version by going into 'Firefox Add-Ons' and checking that the plug-ins are up to date.

There were two steps in my last message. Did you do both?

Optional; Remove Java. Then re-install it.

Confirm the above. Probably because Java is NOT supported for xp anymore. see, 1, 2, 3

if you have the latest as FredMcD said above, leave it as it is, and you are OK.

thank you

Yes, I followed both of FredMcD's steps:

First, I uninstalled Java then re-installed it.

Second, I clicked 'Verify Java' again n Java's website but it still would not scan for its own software. As a result, I manually checked the latest Java update on Java's Download website and my version is the latest.

Ideato gave me the info that I was seeking-Java is obviously no longer supported for XP so I will have to search for future Java updates .through Firefox Add-Ons.

Which Download should I choose?

Choose the 32-bit download to use with a 32-bit browser. Choose the 64-bit download to use with a 64-bit browser.

If you use 32-bit and 64-bit browsers, you need to download both 32-bit and 64-bit Java.

System Requirements

Windows 8 Desktop
Windows 7
Windows Vista SP2
Windows Server 2008 R2 SP1 (64-bit)
Windows Server 2012 (64-bit)

Note: As of April 8, 2014 Microsoft stopped supporting Windows XP and therefore it is no longer an officially supported platform. Users may still continue to use Java 7 updates on Windows XP at their own risk, but support will only be provided against Microsoft Windows releases Windows Vista or later.
