About the Merge Modules Page
The Merge Modules page lets you add merge modules to an installation, edit settings for
merge modules that you’ve already added, and remove merge modules from an
installation.
See:
Adding a Merge Module to an Installation.
Editing Merge Module Details on page 346.
About Merge Modules on page 330.
Adding a Merge Module to an Installation
Use the Merge Modules page to add merge modules to an installation. By default, merge
modules are not installed with Wise for Windows Installer. However, you can create
merge modules or use the Download Redistributables wizard to obtain third-party merge
modules and merge modules authored and tested by Wise Solutions. See Downloading
Redistributable Files on page 39.
When deploying software via a merge module, keep update considerations in mind.
Example: If you deploy MSDE via a merge module, end users cannot use Microsoft’s
MSDE security patches to update that installation of MSDE. Microsoft patches only
operate on software packages installed by .MSI. You would have to incorporate the
MSDE patch changes in an update to your own application and distribute it to your end
users. This could cause security and timing issues for your end users.
To add a merge module:
1. Select Installation Expert > Merge Modules page.
2. From Current Feature, select a feature or condition. (Because any item you add
must be assigned to a specific feature, you cannot add an item when All Features
is selected.)
