Chapter 8: Organizing Files for Your Installation
Including Redistributables in Your Installation
InstallShieldPrerequisitePath when the default targets file is used. To specify multiple paths, use an
ordered array of paths.
Instead of using hard-coded paths, you can use path variables in paths, as in the following example:
\SetupPrerequisites,\MyCustomPrerequisites
The Redistributables view lists the names of the InstallShield prerequisites that correspond with the .prq
files that are present in the various search paths that are specified on the Prerequisites tab of the Options
dialog box. If the same .prq file is in multiple search paths, InstallShield shows only the first instance
that it encounters. InstallShield first searches each path that is listed in the per-user setting on the
Prerequisites tab. Then, InstallShield checks each path that is listed in the machine-wide setting.
At build time, if your project includes one or more InstallShield prerequisites, InstallShield searches the
specified locations and includes the appropriate InstallShield prerequisites in your release as needed. If
the same .prq file is in multiple search paths, InstallShield includes in the build only the first instance
that it encounters. It uses the following order to search for .prq files:
1. InstallShield checks the paths that are specified through the -prqpath command-line parameter, the
PrerequisitePath .ini file parameter, or the PrerequisitePath parameter on the InstallShield task.
2. InstallShield checks each path that is listed in the per-user setting on the Prerequisites tab.
3. InstallShield checks each path that is listed in the machine-wide setting on the Prerequisites tab.
4. If no paths are specified in any of the aforementioned locations, InstallShield checks the default
location (InstallShield Program Files Folder\SetupPrerequisites).
Specifying a Run-Time Location for a Specific InstallShield Prerequisite
InstallShield enables you to specify a different run-time location for each InstallShield prerequisite in
your project.
Task To specify a different location for each InstallShield prerequisite in your installation:
1. In the View List under Specify Application Data, click Redistributables.
2. Select the check box for one of the InstallShield prerequisites that you want to include in your
installation.
3. Right-click the InstallShield prerequisite and click Properties. The InstallShield Prerequisites
Properties dialog box opens.
4. In the Build Location list, click the appropriate option.
Note that the location that you specify can be overridden at the release level. To avoid overriding the
value that you selected for an individual InstallShield prerequisite, the InstallShield Prerequisites
Location setting at the release level setting must be set to Follow Individual Selections. For more
information, see Specifying the Run-Time Location for InstallShield Prerequisites at the Release Level.
Building a Release that Includes InstallShield Prerequisites
When InstallShield builds a Setup.exe file for a project that does not include any prerequisites, it starts
with the base Setup.exe file stored in the following location:
