Windows Installer Editor Reference
Note
The end user's action on the Installation Type dialog box determines the
INSTALLLEVEL property. To see how this works, go to Setup Editor > Dialogs tab
and click the Installation Type dialog in the list. Double-click the Typical/Complete/
Custom radio button, and you see that the end user's choice in this radio group sets
the property InstallMode. If you then double-click Next on the Installation Type
dialog box and view the Events tab, you see that, based on the InstallMode value,
the installation property INSTALLLEVEL is set to either 3 or 1000.
Display
Specify if and how the feature is displayed to the end user on the Select Feature
dialog box during installation.
Invisible
Do not display the feature.
Visible and Expanded
Display the feature and its children.
Visible and Collapsed
Display the feature but not its children.
To expand or collapse a selected feature's children, display hidden features, or
display the features' titles rather than the features' names, use the right-click menu
on the Features page.
See Features Page on page 110.
Attributes
Specify the default for the feature in the installation. The end user can change the
default.
Favor Local
The feature should be installed on the destination computer.
Favor Source
The feature should be run from the source CD or network directory. This means
the feature is available to the application, but is not installed on the local hard
drive. When the feature is invoked, your application must call Windows Installer
functions (example: MsiGetComponentPath) to locate and read the necessary
files from the installation source, which might be a CD or shared network
directory. A typical use of this option would be to specify a clip art library to run
from the source. Then you must code your application to try to read from the
installation source when the end user tries to use the clip art library.
Favor Parent
The feature should use the same attribute setting as its parent feature. If you
select this option, you must also set the installation to generate uncompressed
external files that can run from the source.
See Adding a Media Item
Advertising
Specify the default setting for how this feature supports advertising. If a feature is
advertised, it is not installed, but it appears to be installed to the end user. Example:
The end user might see shortcuts or menu options for an advertised feature, or the
system might have certain entry points to the feature, such as a registered file
extension, that can perform installation-on-demand of an advertised feature.
