Chapter 8: Organizing Files for Your Installation<br />

Including Redistributables in Your Installation<br />

The <strong>User</strong> Interface for an Installation that Includes <strong>InstallShield</strong> Prerequisites<br />

If a target system needs one or more setup prerequisites to be installed, the setup launcher typically<br />

displays the setup prerequisite dialog before the main installation starts. This setup prerequisite lists all<br />

of the nonhidden setup prerequisites that are missing from the target system. When an end user clicks<br />

the Install button on this dialog, the setup launcher launches the necessary setup prerequisite<br />

installations. If one or more of the setup prerequisites is marked as requiring administrative privileges<br />

and the installation is run on a system on which <strong>User</strong> Account Control (UAC) is enabled, the Install<br />

button on this dialog has the shield icon to alert the end user that elevated privileges are required.<br />

Figure 8-1: Sample Setup Prerequisite Dialog that Shows the List of Setup Prerequisites that Need to Be Installed<br />

If a setup prerequisite is configured to be hidden, it is not listed in the setup prerequisite dialog, but it is<br />

still installed. If all of the setup prerequisites in an installation are hidden, the installation displays the<br />

setup launcher’s standard initialization dialog instead of the setup prerequisite dialog.<br />

If the file that a setup prerequisite installation launches is an .msi package and the prerequisite is<br />

marked to show progress, the user interface shows a status bar, along with installation progress<br />

messages from Windows Installer, while the prerequisite is being installed.<br />

If a setup prerequisite is configured to be optionally installed by the end user, the setup launcher<br />

displays a message box that enables end users to choose whether to install the setup prerequisite.<br />
