I am having difficulties installing FileMaker Pro 8 via an msi app. I have an mst file setup for entering the company name and product key. If I install the app using a full interface, all information populates the fields correctly, and the app installs fine, but when I try using either reduced or default, I get a 1603 error within 10 seconds, and the log file shows that the app appears to be erroring out at the getinstallcode portion of FileMaker's msi.

Any suggestions would be great as I need to deploy this app to approx 50 workstations.
