Check if Reboot is required

[heiner_violet]

Hello,
I'm working with IS 2008, Basic MSI.
How can I get to know if a reboot is required after the SetupCompleteSuccess Dialog?
I need to know this because in my setup, there is a Custom Action that starts another setup after the SetupCompleteSuccess-Dialog. I would like to start this follow-setup only, if no reboot is required. What is a good way to achieve this?

Thanks for any suggestions, H.

I did as suggested above: a vb-Script CA at the end of the UI-sequence detects the pending reboot and sets a property REBOOT_REQUIRED. I inserted a ScheduleReboot-Action at the end of the UI sequence. This CA has condition "REBOOT_REQUIRED And Not CheckBoxLaunchNextSetup". I removed the ScheduleReboot-Action at the end of the install-execute sequence.
Problem: Running the setup, a reboot is prompted at the end of the setup, regardless of the users choice of CheckBoxLaunchNextSetup.
The log-file indicates that the ScheduleReboot-Action at the end of the UI-sequence is skipped (as intended). But at an earlier point the ScheduleReboot-Action is executed.

Does anybody know, where the reboot prompt at the end of the setup is scheduled and how to suppress it?

Any hint would be greatly appreciated, H.

In the msdn2 help the following is stated: "If the installer determines that a restart is necessary it automatically prompts the user to restart at the end of the installation, whether or not there are any ForceReboot or ScheduleReboot actions in the sequence."
So I will try to use the REBOOT property in order to control the reboot at the end of the setup.
