Multiple Transforms and Their Supercedence

Command line to apply multiple transforms:

Msiexec.exe /i {path}.msi TRANSFORMS=T1.mst;t2.mst

Value Supercedence:

If t2.mst contains any property or any update that t1 has made, the installation will take the final transforms value.

Ex: If t1.mst sets a reg value HKCU\Software\Test\Enviorment =0

And if T2.mst sets a different value to the same registry HKCU\Software\Test\Enviorment =1

then the instalaltion will take the reg value as 1.
