Note
Multiple instance installations are supported only by the versions of Windows Installer
released with Windows XP SP1 (2.0.2600.1106), Windows Server 2003 (2.0.3790.0), or later.
Like other types of transforms, an instance transform must be applied to a base .MSI or
patch during installation using a command line option; it cannot be applied beforehand.
On the command line, type the following:
msiexec /i Application.msi TRANSFORMS=Instance.mst MSINEWINSTANCE=1 /
qb
where Application.msi is the name of the .MSI, and Instance.mst is the name of the
transform.
For additional examples, search for “Installing Multiple Instances with Instance
Transforms” in the MSDN Library (msdn.microsoft.com/library/).
