Pass Return Code Across Dependent Applications
When installing an Application with dependencies, the ability to capture the dependent Apps return code and then perform a set of actions (run a custom script, additional child dependency, etc.) or have a series of extra settings that can be configured (wait until reboot/logon/additional action complete), would be very helpful.
For example: AppA has a dependency that will require a reboot but it must be initiated by the user. The ability for the primary App to get that return code and then "Hold until reboot" would be very helpful.
