The Edit Components Properties Page

This dialog enables you to edit properties for multiple components.

General

Condition

A Windows Installer condition which is evaluated and the result determines the installation of the component. If the condition is null or is evaluated to false, the component is not installed. Use the [ ... ] to edit the conditional statement.

Do not register this component with Windows Installer

If this option is selected the component will have an empty GUID and thus it will not be registered. This means that the component cannot be removed, repaired or patched by the installer. This might be useful if you intend to service/uninstall the component yourself (using a custom action, for instance).

Attributes

• Run From Source Only
  The component can only be run from source.
• Optional
  The component can run locally or from source.
• Shared Dll Reference Count
  Windows Installer increments the reference count in the shared DLL registry of the component's key file.
• Permanent
  This component is not removed during an uninstall.
• Transitive
  Windows Installer reevaluates the statement from the Condition field after a reinstall.
• Never Overwrite
  The component is not installed or reinstalled, if a key path file or a key path registry entry for the component already exists.
• 64-bit Component
  This component is marked as a 64-bit component.
• Disable registry reflection
  This option applies only to 64-bit systems with Windows Installer 4.0. If this option is not enabled for a component, Windows Installer makes the associated registry changes in both 64 and 32 bit registry views.

If registry reflection is disabled the changes are performed only in the targeted view.
