"Error while registering the Java 2 Runtime Environment registry keys"

I am getting the above error when trying to install the 1.3 JRE
(installed with the 1.3 plug in which I need). As part of my
development I have been installing and uninstalling the JRE multiple
times. Then, I got the above error when trying to install it, and now
it appears to be installed but I cannot uninstall it. When I try to
uninstall it, it just remains, and when I try to install it again I get
the above error. I have tried cleaning up all javasoft registry
entries, but it doesnt seem to have helped. Can anyone help me either
completely uninstall the JRE so I can do a clean install or help me get
rid of the error above when I install. Is there some registry entries I
should be looking at? Anything else? this is quite urgent as I need to
test my applet with the plugin installed and not installed - and I
currently cant uninstall it. Any ideas?
Thanks for your help

Can anyone help me either
completely uninstall the JRE so I can do a clean install or help me get
rid of the error above when I install.

My rule of thumb after getting screwed many times is to have only one
JRE /JDK at a time installed on a machine.

If you do that, uninstalling the old before installing the new, all
works smoothly.

You can't then run into problems with code from two different JRE
versions getting muddled together.

Start by uninstalling and deleting the various JRE/JDK directory
trees.

Delete any copies of java.exe or javaws.exe anywhere you find them.

If your registry is hosed, see my notes on the Java entries. Just
delete them all. http://mindprod.com/jgloss/registry.html

Now start from scratch and install one JDK or JRE.

I have an install script I run after installing Java to fix up the ext
directories, check the classpath, path etc.

The follow the instructions here on testing your JRE.
