Their reply sounds like a canned version of what InstallAware does itself. InstallAware is the only setup vendor to offer MSIcode technology, which far excels the capabilities of SetupScript. Unlike SetupScript which is separate from the MSI database and engine, MSIcode is integrated with Windows Installer and actually produces your setup MSI file from your script commands. MSIcode also lets you do certain things which no other tool can with Windows Installer:
* One-click patch construction
* 32 and 64 bit hybrid or runtime-switching installs
* Runtime feature definition (not only selection)
* Runtime license validation
* Easy multiple instance installations, even on platforms MSI cannot do this on
* Runtime branching and decision making with MSI (another InstallAware exclusive)
SetupBuilder cannot offer this level of flexibility, because they use WiX (a language with a very difficult learning curve) to produce their MSI files, and their SetupScript is completely external to this process - its a separate script that doesn't know anything about what's going on with your actual files/registry keys, so it cannot command MSI actions at runtime.
Because of this, its very hard for you to inject runtime intelligence into your installations with tools like SetupBuilder - whereas with InstallAware, there's only one script which is updated seamlessly by the visual designers, so there's less to learn and you have more real-time control and flexibility.
This is why Borland migrated to InstallAware from InstallShield (like 80% of our customers did), because it enabled them to integrate all their separate product editions, languages, and IDEs inside a single setup package, with the correct runtime licensing and intelligence to install only the features that are chosen/licensed for the end-user. You can calculate the cost savings from that...
I suggest you read our MSIcode Scripting whitepaper here:

Upon reading, you might that a lot of our marketing collateral has been "borrowed" by SetupBuilder

Except that our technology is better integrated with Windows Installer and easier to learn.
