Installing the Merge Module Feature
The Brooktrout SDK (sdk_windows.exe) includes the Merge Module
feature that installs all the *.msm files. When you launch
sdk_windows.exe, the files (merge modules) install under
[INSTALLDIR]\mergemodules
where INSTALLDIR identifies the
location that you select for storing the Brooktrout SDK package. The
mergemodules
folder also includes a readme.txt file that briefly
describes the merge modules.
You choose to install the
Merge Module
feature by selecting it in the
Custom Setup Type
screen.
Integrating the Modules
Microsoft® Software Merge (*.msm extension) module files cannot be
directly installed on a system. The feature requires you to merge
modules into an installer for each application that uses the
component. This merging process ensures that the application
installs components consistently, and it eliminates problems such as
version conflicts, missing registry entries, and improperly installed
files.
After installing your Brooktrout SDK, copy the merge modules to a
location accessible by your install project.
The next step requires you to add all the dependent merge modules
to your project and set their destination paths.
Note:
The design of the Brooktrout merge modules excludes any
dependencies due to a defect in the InstallShield Developer 8.0
IDE. This defect prevents a developer (Dialogic (formerly
Brooktrout) as the developer of the merge modules) from
setting the destination path of dependent merge modules.
Without a specified destination, InstallShield uses a default
destination that installs the merge module files under:
[WINDOWS_VOLUME]
where WINDOWS_VOLUME is the drive where the operating
system is installed.
