Hi Rob, Please correct me if I'm wrong. Elevation is done by the "chained" installers itself and not Burn ? If so, and I run several MSI + Exe packages thereafter each wants elevation. Then I'd highly vote at least for an ability to embed an admin manifest without need of mt.exe.
I mean I fully understand the concept of elevating just when needed but from my point of view I need such a Bootstrapper elevation to run all subsequent installers without additional UAC dialogs if needed.
