Creating a Configurable Merge Module
Windows Installer Editor Reference
The components you select are removed from this installation, compiled into the new
merge module, and re-inserted in the form of a merge module. The new merge module
is also available to other installations.

Available Tabs and Pages in Merge Modules
Available in merge module files (.WSM, .MSM) only.
To create a configurable merge module, you add configuration items to a standard
merge module. On the Substitutions page, you specify the:
Substitution item, which is the field that can be configured.
Configuration item, which determines how a field can be configured.
This creates a substitution value, which consists of one or more values specified by
configuration items. When a configurable merge module is added to an installation, the
installation author can specify values for the substitution item based on the
configuration item settings.
See
Adding a Merge Module to an Installation
Configurable merge modules are supported only by Windows Installer 2.0 or later.
For information on creating a standard merge module, see
