Merge Modules and Transforms
The merge modules are added to this installation. If any of the merge modules contain
dependencies, Windows Installer Editor tries to add them by looking in the default
merge module directory.
See
Setting Dependencies for a Merge Module
on page 367.
If a dependency merge module cannot be found, you are prompted to download it.
During compile, the merge modules are merged into the installation, so that the
resulting .MSI contains both the changes defined in the standard installation as well as
the changes defined in the merge modules. If your compile fails because of merge
module errors, the errors appear in the Task List.
To remove a merge module from an installation, select the merge module on the Merge
Modules page and click Delete. If the module is included with more than one feature, it
is only removed from the installation when you remove it from all features.

Editing Merge Module Details
To edit merge module details
1. Select Installation Expert > Merge Modules page.
2. From Current Feature, select the feature or condition that contains the merge
module to edit.
3. Double-click a merge module.
The Merge Module Details dialog box appears. It has one tab if you double-clicked a
standard merge module and two tabs for a configurable merge module.
4. Click the Settings tab and change the dialog box’s settings as needed:
Module Source Path
To get the same merge module (with the same GUID) from a different location,
enter a full path to the merge module.
Destination Directory
Select the destination directory for files in the merge module that are not
installed to a predefined directory. If there are no files in the merge module’s
Application directory and you want to leave this blank, select <none>.
Feature
If the installation contains multiple features, a list of features appears. To add
this merge module to other features, mark their check boxes.
If multiple features in the installation depend on this merge module, you should
add it to all of them. Only one copy of the merge module is installed on the
destination computer regardless of how many features include it.
5. If the merge module is configurable, the Merge Module Details dialog box has a
Configuration tab. To change configuration values:
Click the configuration tab.
In the list box, select the name of the item to configure.
