How Transforms are Included in an App-V Package

InstallShield 2015 » Microsoft App-V Assistant

Edition: The Microsoft App-V Assistant is included in the Virtualization Pack.

The Microsoft App-V Assistant supports the inclusion of transform files with Windows Installer packages in an App-V package.

How transforms are applied when building an App-V package—When you are building an App-V package, transforms that you have specified are automatically applied to the base Windows Installer (.msi) package to create a temporary package, and then the App-V package is generated from that temporary package.
Creating a new transform—You can create a new transform in InstallShield, and then build an App-V package from that transform file. When you create a new transform file in InstallShield, you specify the root .msi file in the Open Transform wizard. The steps you take to generate an App-V package after using that wizard are exactly the same as if you were editing a Windows Installer package in Direct Edit mode.
Converting a Windows Installer package with existing transforms—If you have a Windows Installer package and one or more existing transform files, and you want to include these transforms in the App-V package, you need to open one of the transforms in InstallShield (rather than the .msi file). The Open Transform wizard will open, and you will be prompted to specify the root .msi file and which of the existing .mst files you want to include. The steps you take to generate an App-V package after using that wizard are exactly the same as if you were editing a Windows Installer package in Direct Edit mode.

Caution: All of the transforms that you add to an App-V package must be located in the same folder as the Windows Installer .msi package so that they can be accessed when the App-V package is built.
