Windows Installer Editor Reference
set in this drop-down list determines the default state of the feature during installation.
The drop-down list provides a way to set common options quickly. The icon itself
provides a visual cue that indicating which options have been set.
The drop-down list options are a subset of the options that are available in the Feature
Details dialog box, which you access by clicking the Details button at the right of the
Features page.
Note
The first four options in the feature's drop-down list set the default only; the end user
can change the default during installation. To prevent the end user from being able to
change the defaults you set here, you can turn off the Select Feature dialog box on the
Dialogs page, use the Feature Details dialog box to set features to be required, or set
features to be hidden from the end user.
To set options for a feature
Click the feature's icon and select an option. You can select only one of the first four
options, but you can set the fifth option, Hidden from user, in combination with any of
the first four options.
Will be installed on local hard drive
Make the feature default to being installed on the local hard drive. (This option
corresponds to setting Favor Local in the Attributes drop-down list on the Feature
Details dialog box.)
Will be installed to run from source
Make the feature default to being run from source. (This option corresponds to
setting Favor Source in the Attributes drop-down list on the Feature Details
dialog box.)
If a feature is installed to run from source, it is available to the application and
visible to the end user, but is not actually installed on the local hard drive. When the
feature is invoked, your application must call Windows Installer functions, such as
MsiGetComponentPath, to locate and read the necessary files from the installation
source, which might be a CD-ROM or shared network directory. Example: Use this
option 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.
Feature will be installed when required
Make the feature default to being advertised. (This option corresponds to setting
Favor Advertising in the Advertising drop-down list on the Feature Details dialog
box.)
If a feature is advertised, it is available to the application and visible to the end user,
but is not actually installed on the hard drive. If the installation source, such as a
CD-ROM or shared network directory, is available to the destination computer, the
feature is installed when the end user invokes the feature. If the installation source
is not available, the end user is prompted for the installation source.
Entire feature will be unavailable
Prevent the feature from appearing during installation and from being installed.
(This option corresponds to setting Never Install This Feature on the Level drop-
down list on the Feature Details dialog box.)
