File Wizard: Uninstall Options

     


  In this step of the file wizard, you select options regarding the uninstallation of the selected files and directories.
  The following uninstall options are available:
  • Uninstallation policy
    This setting determines how the uninstaller decides whether an installed file should be uninstalled or not. The uninstallation policy can be one of:
    • If created
      If the file or directory was created by the installer, it will be deleted.
    • Always
      The file or directory will always be deleted regardless of whether it was created by the installer. Please be careful when choosing this option, since deleting directories that were not created by the installer can have severe unintended consequences.
    • Never
      The file or directory will not be deleted ny the uninstaller.
    • If created, but not for update
      If the file or directory was created by the installer, it will be deleted. However, if the uninstaller is running as part of the update (invoked by an "Uninstall previous installation" action), the file or directory will not be deleted.
    • Always, but not for update
      The file or directory will always be deleted regardless of whether it was created by the installer. However, if the uninstaller is running as part of the update (invoked by an "Uninstall previous installation" action), the file or directory will not be deleted. Please be careful when choosing this option, since deleting directories that were not created by the installer can have severe unintended consequences.
  • Shared file (Windows only)
    Microsoft Windows has a concept of "shared files" where a usage counter is monitored for each file or directory. When the usage counter reaches zero the installer will delete the file or directory. This is especially useful if you install DLLs into the system32 directory that are shared by multiple applications.
