  • Windows Installer does not provide an easily timed mechanism to delete registry keys. This action will not execute through the Windows Installer engine and is provided as a convenience for the setup developer.
  • We recommend you create all registry keys used by your application as part of your setup. Doing so assures Windows Installer will automatically remove all such keys upon uninstallation.
