Obtaining Blank Merge Module Databases

Obtain a blank merge module database. You can use the file Schema.msm provided with the Windows Installer SDK as a starting database for your merge module. For more information, see Windows SDK Components for Windows Installer Developers.

Developers should author merge modules using the simplest database schema that installs their components. The use of a simple schema ensures the greatest compatibility for the merge module. Merging a merge module into an installation package with a different database schema usually results in merge conflicts.

For a complete list of all the required and optional tables in merge modules, see Merge Module Database Tables.
