We have a product install that requires multiple Prerequisites and some of them require a reboot before continuing the main product install.
Is there a way or a helper app that will schedule the reboot to occur after all prerequisites have been installed instead of having it perform a reboot after each prerequisite is installed?
Hmm. There's a prerequisite behavior option that's fairly close: reboot after installation. However it sounds like you want a reboot after all prerequisites, but before main installation. If that sounds correct I can create an enhancement request for this.
Yes that is exactly what we want. The main reason for this is that if you have a few prerequisites that all require a reboot then we would perform to have all the prerequisites installed first and then perform the reboot. This avoids having mutilple reboots required before we even get to the main application install.
So if you can have a request to have that functionality added that would be great.
Great. I've filed a request for such an option under #IOA-000055085. This would work similarly to the existing delay reboot, but would batch them (with cooperative prerequisites) only until after all prerequisites have been installed.
In the meantime, you might be able to get similar behavior if you can create an executable that reads the RunOnce key for relevant entries, and schedule it last as a hidden prerequisite with reboot-now settings for an exit code that indicates it found such entries, or perhaps with Launch Conditions or Custom Actions in the MSI itself.
