In-Depth Information
Beware of this step, though. It's better to leave the unused references to the application
in the Registry if you're not absolutely sure what to delete. You may fi nd such informa-

Often it's possible to reinstall the application over a corrupt uninstall; the installation
software will do the necessary work for you to repair it. Then, after the installation has
been repaired, you can try again with the Uninstall utility.
