Java SE (Java Platform, Standard Edition)

I mistakenly installed 64 bit Java 6 Update 20 on my 64 bit computer and then realized that I needed the 32 bit since I use IE 32 bit.

I used the Control panel to unistall it, but it gives me error 1723. i tried to install 64 bit Java 6 Update 21 hoping it would over-write the problem files and then I could uninstall it. Still get an error 1723.

I tried to install J6 update 21 32 bit and it worked! ... but the control panel icon for java is a blank document. If I click that white icon, it gives an error saying Application not found. The Programs control panel now has both J6 u20 64 bit and j6 u21 32 bit but I still get 1723 error when I uninstall the 64 bit program.

I have searched the Internet. Most people say to use the Windows installer clean up but the link to that page goes to something that handles only office clean up. Elsewehere you can find people saying that Apple withdrew the cleanup utility.

Is there a utility that "completely removes all versions of Java" the way there is for MacAfee and Norton products?

Anybody have any ideas? Do I just delete a directory? What about remnants in the registry?
