I keep getting reminders that a Java update is available, but when I try

This has been going on for some time now. Assuming that Java knows how
to send a good file, I might have some sort of interfering setting in my
computer. Being hopeless about the security settings, I'm looking for
advice.

Anyone? All help gratefully appreciated.

Contrary to assertions by Oracle, a new version of Java cannot be
installed correctly without first removing any old versions.

1.  Remove all prior versions of Java.

2.  Reboot.

3.  Download the current version of Java from <http://www.java.com/en/>.

4.  Install the new version of Java.

5.  Test the installation at
<http://www.java.com/en/download/installed.jsp>.

O.K., I did all this. After installing, I got the message "Installation
Complete". Sounded good. Did the test. Result; "Java not detected". Went
to the Try Again step, result: "Java is disabled or not installed".

Java IS listed in Programs and Features in the Control Panel. Its icon
also appears in P and F, and will open the Java control panel, where it
IS activated for the browser. However, it does NOT appear in the Add-Ons
list nor in Help-About Plug-ins.

Since I have a 64-bit OS, that's what I installed. Thinking that SM was
32-bit (?), I also tried to install that version, but get the message
"(File Name) is not a valid Win 32 application".

Try downloading the 32 bit offline installer from
http://www.java.com/en/download/manual.jsp
and check the signature to make sure it downloaded ok
  (open windows explorer, right click jre-8u45-windows-i586.exe, left
click properties, select digital signatures tab, hilight the one &
only signature, click details - you should get "The digital signature
is OK")
install that & reboot.  java should at least show up in the plug-ins
pane.  It's been a while since I've had java installed, so I don't
remember if you have to enable it in SM or what

Hurray! It worked. Followed your steps, as well as David's (remove 64-bit first), and Java has now reappeared in Add-Ons Manager and in About Plug-Ins.

Thank you, very much!
