I am trying to install Rhapsody 8.2.1 using the "silent install" method.  I read through the IBM documentation and I kick off the script and things look good initially.  The "Preparing to install" window pops up.  The "Rhapsody Welcome" pops up and that's it. It just sits there waiting for you to click "Next".

Here is the script we are running.

The log file shows nothing but ends with the following:
