Some users manually delete programs from their computers. This
unfortunately does not remove keys in the registry and leaves the
uninstallation entry in the list although the application has been removed
from your computer already. To remove the entry from your system
mark the application in the list and click the Delete button.
To search for an installed program choose the Search function. Enter
the name of the application you're looking for and click Search. The
tool will mark the first entry in your uninstall list matching your query.
