You will need a tool that creates and maintains Windows Installer .msi files to make use of the Merge Modules. We used Installshield Express 3.03 to test out the merge modules. With Installshield Express 3, all you need to do is to copy the .msm files into the "objects" subdirectory in the Installshield 3 installation directory. They are then available for use in the list of "Objects/Merge Modules" as soon as you start Installshield. Note that Installshield treats Merge Modules as single units.
Other tools will have different strategies for incorporating Merge Modules. Please refer to the product documentation.
The Merge Modules have also been tested under Installshield Developer and Wise for Windows Installer.
For Installshield Developer (and later versions of Installshield Express), it is best to copy the merge modules to a separate directory and to set the Merge Module search path to include this directory. This is done from Installshield (Express of Developer) from the "File Locations" tab in the "Tools->Options" dialog. All you need to do is to add the path to the directory in which the InterBase merge modules are located to the list of "Merge Module Locations". The next time you view the Merge Module gallery, these InterBase Merge Modules will be available in the list of Merge Modules.
For Wise for Windows Installer, the installation process is very similar, except that the search path for Merge Modules is set from the "Directories" tab in the "Edit->Preferences" dialog.
