Decrementing counter to disable shutdown. If counter >= 0, shutdown will be denied. Counter after decrement: -1

I use msiexec.msi line command to run a msi file created using WIX, the setup is runn with the parameter /qb and /promptrestart, but if I get the line "Decrementing counter to disable shutdown. If counter >= 0, shutdown will be denied. Counter after decrement: -1" in log the prompt didn't appear. The exit code of the msiexec process is 0 not 3010 (need restart) but the service that must be uninstalled remain in services.msc mark开发者_高级运维ed for deletion and some time even running (during install/uninstall services.msc is closed). After restart the computer all works fine.

Could you please tell me how to detect that a restart is required?

Windows Installer is not very reliable when it comes to handling reboots. A good approach is to determine yourself if the install or uninstall process requires a reboot and trigger it manually if it does.

To perform a reboot you can use the REBOOT property.

You might also want to ensure the service isn't running through a custom action.
