of applications installed and available for uninstallation in the ''HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall'' registry key. The value in the DisplayName key of a particular package is whatused for 's matched by this check'exists'' checks, and DisplayVersion for checks against the version.
pre-1.1.0 versions of WPKG have only one condition available for this option: ''exists''.
