About Transforms (.mst)

AdminStudio 2023 | 25.0 | Application Manager

Application Manager supports the import of Windows Installer packages (.msi) with associated transforms (.mst). A transform is a collection of changes applied to an installation. By applying a transform to a base installation package, the installer can add or replace data in the installation database. The installer can only apply transforms during an installation.

The installer registers a list of transforms required by the product during the installation. The installer must apply these transforms to the product’s installation package when configuring or installing the product.

A transform can modify information that is in any persistent table in the installer database. A transform can also add or remove persistent tables in the installer database. Transforms cannot modify any part of an installation package that is not in a database table, such as information in the summary information stream, information in substorages, information in nested installations, or files in embedded cabinets.
