I'm running Zen 6.5 and I'm trying to deploy an application that has an
MSI file. (Acrobat 6.0 Pro) I'm getting error code 1603 when Application
Explorer tries to launch the installation.

I've deployed other applications that have msi files (Microsoft Office)
along with a MST file (transform) and that worked just fine.

I created an MST file for it and I've tried deploying it with and without
the MST.
