We\'ve decided to create a custom bootstrapper for our deployment solution. We are currently re-writing and re-designing our deployment strategy for all of our products. Sad
Frankly, Burn isn't going to be done for at least a year. You already have InstallShield and IMO it has the best off the shelf bootstrapper currently available. I'd scope your requirements back and make it fit the box. Pretty much everything I read from you can be done using InstallShield if you learn to push it to it's limits.
