(Taken from the MSI SDK under TRANSFORMS property)
“For example, to apply three transforms to a package, set the TRANSFORMS [property] to a list of file names or to a list of full paths.” ie: TRANSFORMS=transform1.mst;transform2.mst;transform3.mst
MSIEXEC /i MyApp.MSI TRANSFORMS=transform1.mst;transform2.mst;transform3.mst
