I have been using a locally-deployed applet for some time with 32-bit Java 6 
on the client and it has been working fine.  Since upgrading the client to 
64-bit Java 7 I find that the applet cannot detect that Java is installed 
and insists on downloading and installing a 32-bit JRE.  I have since 
discovered that the same thing happens even I downgrade to 64-bit Java 6.

The applet is deployed using JNLP and I mean an applet that runs inside the 
browser, not a Java Web Start "application".

The auto download of the JRE is being triggered because I include this 
script in the HTML:

<script src="http://java.com/js/deployJava.js"></script>

I run the applet using:

deployJava.runApplet(attributes, parameters, '1.6');

and I have tried using an argument of '1.7' as well to no avail.

The JNLP contains the following <java> tag:

<java version="1.6+" href="http://java.sun.com/products/autodl/j2se" 
max-heap-size="768m"/>

and again I have tried specifying "1.7+" as well.

So what's the trick to deploying applets using JNLP and 64-bit Java?

And loving it,
