Hello and welcome to Advanced Installer forums,
I'm afraid I don't fully understand what you mean? Can you please give us more details about your scenario (maybe exemplify)? Also, can you tell us what version of Advanced Installer you are using?
Please keep in mind that if you have chained packages or
prerequisites added to your package, then the main installation should continue after reboot.
If your are using a
custom action to launch the related reboot script, then you should schedule it after "Install Execution Stage" -> "Add Resources" action group. Also, the custom action should run as deferred with no impersonation.
All the best,
Daniel
