From your Posts, I gather that you've been installing from the "
online installation", instead of downloading the previously recommended "
offline installation" for later install.

Offline Installation, Multi-language jre-1_5_0_11-windows-i586-p.exe 15.80 MB <—
get this one

Please Post back to this thread, if you think you have other JRE items showing in Windows Installer Cleanup Utility,….
before taking any action to apply Windows Installer Cleanup Utility to any item other than those indicated by highlight in the picture above.
_____________
Now, from reading the MS Knowledge base article linked above, you know that applying Windows Installer Cleanup Utility to an item in the list (illustration above), the "program itself" (in your case, JRE 1.5.0.11 and or JRE 1.6.0.0) you are not "uninstalling the program", rather you are removing all traces that it has been through the installation procedure, *[while leaving the actual program in place on your machine]*
Of course, it will no longer appear in Control Panel - Add/Remove - and that's just fine.
Therefore………… You will now be able to make a "new installation" of either/both from the
offline installation file that you've already saved to a location that you can easily remember.
Please do so now. [install JRE 1.5.0.11 etc.]
Remember to allow the JRE to be installed into exactly the same location that it is presently installed.
_______________
By performing the above, you should now be able to use Control Panel - Add/Remove to "Uninstall" the program itself.
Please do so now. [Uninstall JRE 1.5.0.11, etc]
_____________
Once you have performed the above procedures, you can then install the desired "single instance" of JRE 1.6.0.0.
Please do so now. [install JRE 1.6.0.0]
Please post back with your progress.
