Java 6 update 3 not running with Vista

Question

Previously I have had not problems with getting Java applets to work, but I just got a new computer with a Vista operating system and I cannot get any applets to work. I tried uninstalling and reinstalling the lastest JRE from Java's website many times. I also went through their help and made sure the configureations matched that of IE7 which I am using. I have tried older version and even update 4, but I cannot even get the java test machine to work. There is just a red X that eventually shows up after a long wait. Currently, I have update JRE 6 update 4. I have not made any major changes to my computer as it is only a few days old, so I figure that it must be something that is not compatible with Vista. Below is what my Java Console reads after it fails to run when I test my VM on Java's website at http://www.java.com/en/download/help/testvm.xml :
load: class testvmDynamicJavaCom.class not found.
java.lang.ClassNotFoundException: testvmDynamicJavaCom.class

I have a similar post on this subject goto "gordon freeman" java 1.6.0_06 will not run in Vista.
On my system there is a workaround if you open control panel/user accounts, then turn user account control on or off, untick user acccount control and restart the machine then goto website www.javatester.com to test if appelets run! I leave user account control on until I have to goto java website and then disable visit site and then renable this requires 2 restarts everytime I visit a java site. The problem is some sort of permissions issue created by either corruption of the registry by remnants of previous versions or configurations of previous versions it goint ot take me years to work it out. None of the turkeys at Sun have got any idea how to fix this I now am working with Microsoft in an effort to have this problem fixed!
