Paquet Builder 2026.2 - 'Restart Computer' action fails

I use a 'Restart Computer' action after installing a pre-requisite for my setup package.
This works fine with the installer built with previous PB version, but fails with PB 2026.2.
I rebuild the same project and test back-to-back on the same computer. Old version restarts
the computer, new version does not. Need some help here, thanks!

Confirmed: this is a regression introduced in Paquet Builder 2026.2. The "Restart Computer" custom action stops rebooting after a rebuild in 2026.2, while installers built with earlier versions are unaffected. It is now fixed on our side.

A hotfix is available. If you have already emailed support about this, you will find the patch and the exact steps in your ticket reply; otherwise drop us a line and we will send it over. The fix replaces a few runtime files that get embedded into your installer at build time, so after applying it you just rebuild your package and the "Restart Computer" action works again, in both the installer and the uninstaller. It will also be included in the next official Paquet Builder update.

If you want to keep moving right now without applying the patch, a simple workaround is to replace the "Restart Computer" action with a "Launch Program" action that runs:

%SYS%\shutdown.exe with parameters /r /t 10

That reboots through Windows itself and is independent of the action that regressed.
