Thanks for the response.  I'd be happy to take a look at the script if you e-mail it to me at 
afisk@limepeer.com.  I am probably more inclined just to use the older version of InstallShield that we already have, as it has the same functionality, and we had almost no errors with it.  I also already have the old scripts and everything built for it, so it would be nice and easy. 
I'd be very interested to take a look, though.  Thanks again.
