Done the same way in a MST. I don't think you really understand what a MST is. It is just a set of changes. It takes all the changes that you make and saves them. Then when you specify the transform in the commandline, it is telling it to apply those changes to the MSI. That way you are making the changes, but not affecting the original source media. Basically, it just stores your changes in a seperate file, rather than directly applying it to the MSI.We are not trying to say in any way, that what your are suggesting is wrong, so please don't be upset. There is nothing wrong with the way you are doing it. A MST just keeps you from accidentally messing up the original MSI. We are just trying to add a little safety tip to your suggestions. Again, I use Wise Package Studio Professional, so it may be different.... But if you follow your directions for Adobe, or whatever, follow every step, then rather than saving the MSI, you choose Save As.... and save it as a MST.
