Substitute:

Unregister Windows Installer and then reregister Windows Installer. To do this, follow these steps:

1. in the menu 'Start', click on ' execute:.»

2. in the "Open" box, type "msiexec /unreg", and then press ENTER.

3. in the menu 'Start', click 'run '.

4. in the "Open" box, type "msiexec/regserver", and then press ENTER.

If this is insufficient, the I would say to install the Windows Installer Cleanup utility and run that to remove the Java remains Setup files that can cause problems with your current installation.
