Figure 8-2: Message Box for an Optional Prerequisite
Chapter 8: Organizing Files for Your Installation
Including Redistributables in Your Installation
If an installation includes feature prerequisites, the setup launcher does not list them in any prerequisite
dialog. However, the user interface does show progress messages if appropriate. In addition, the setup
launcher displays the optional prerequisite message box if the feature prerequisite is marked as optional.
Silent Scenarios—Suppressed User Interface
The installation can install setup prerequisites and feature prerequisites even if the installation is run
silently. That is, InstallShield prerequisites are supported in any of the following scenarios:
• Silent setup launcher and visible .msi package—The user interface for the setup launcher is
suppressed, but the user interface for the .msi package is visible. For example, the end user might
use the following command-line statement:
Setup.exe /s
In this scenario, the language selection dialog and the setup prerequisite dialog are not displayed.
• Visible setup launcher and silent .msi package—The user interface for the setup launcher is displayed,
but the user interface for the .msi package is suppressed. For example, the end user might use the
following command-line statement:
Setup.exe /v“/qn”
In this scenario, the feature selection dialog and all of the other dialogs of the main installation are
not displayed. However, the end user can set Windows Installer properties such as ADDLOCAL,
ADDSOURCE, ADDDEFAULT, and ADVERTISE from the command line to indicate which
features should be installed.
• Silent setup launcher and silent .msi package—The user interface for the setup launcher and the .msi
package are suppressed. For example, the end user might use the following command-line
statement:
Setup.exe /s /v“/qn”
In this scenario, all of the setup launcher and .msi package dialogs are suppressed.
If the UI sequence of the main installation’s .msi package is skipped, the setup launcher evaluates
Windows Installer properties such as ADDLOCAL, ADDSOURCE, ADDDEFAULT, and
ADVERTISE to determine if any feature prerequisites should be installed, and it installs feature
prerequisites accordingly.
