I have manually uninstalled LimeWire and I cannot install LimeWire 2.3.4

The following message appear:
"Another version of this product is already installed. Installation of this product cannot continue. If you want to configure or remove the existing version of this product use add/remove programs in the control panel. {Error message E499428a-E04F-4683-8A21-42AE6D1C651}"

I have no LimeWire icon to uninstall in the control panel/add-remove programs

What can I do?????

Hey Taliban
Thanks for the reply. I have used the regedit to delete any keys called limewire but my computer still gives me the same message. Can I do something else???
