While doing promoted testing, I found this issue on win2k machine. After that I could reproduce this issue again on the same m/c again. I did installation and uninstallation of JDK and JRE many times (4-5 times). I saw this issue.

1) Jre is installed on the win 2k machine (Java -version shows correct version)

2.) Open the IE and try to launch any applet. You will get message to download the JVM.

When i saw this issue first time, I change the new plugin to old plugin using JCP. After that everything works fine even you revert back to new plugin. After that I could reproduce this issue after several attempts only. So, this time I have not change the plugin and leaving this machine for more investigations. 

Machine name - jdsn8. If need more details abt machine plz email me.

N/A

This problem isn't limited to win2k. The synopsis has been modified to reflect this.
The problem can be reproduced simply by:
- install 6u10 JRE
- run an applet with applet tag
  (optional step, just to check the JRE is fine)
- install 6u10 JDK 
  (note that since JRE has been installed, installing JDK 
   won't offer installing JRE again)
- uninstall 6u10 JDK only.

The cause of this problem is due to while uninstalling JDK, we're removing the registration of the plugin2 SSV module (jp2ssv.dll). 
A simple fix is to add a check in the installer and only unregister jp2ssv.dll if we're uninstalling JRE, not JDK.
