Changing JRE Version for IE

I had a devil of a time finding out how to change the JRE that an applet runs under in IE.  There were registry tweaks and file copies galore but in the end it was pretty painless.

I'm running 1.6.0_20 so your results may vary.

I needed to run an older JRE as an applet in IE.  I had 1.4.2_17, 1.5.0_15 and 1.6.0_20 installed.  In order to change to 1.4 and 1.5 I opened up the Java control panel applet and went to the Java tab.  Under the Java Runtime Environment Settings I selected the View button and unchecked the JREs under the User tab that I didn't want to use.  I restarted IE and it worked like a charm.

Hope it works for you too.
