You could try this.
Download and install the Windows Installer CleanUp Utility, found here:
http://support.microsoft.com/kb/290301
Run Windows Install Clean Up (a shortcut should be in the Start Menu).
Highlight all references to Java SE Development Kit, and click on Remove.
Don't remove other entries for other programs (like Acrobat Reader, for
example), or they will stop working. Then try to reinstall the program.
