I am under some pressure to get some new integration's done so I downloaded a copy of WinToolkit_1.4.29 and tried that with my SFX compilation using a baseline image that included RDP8.0/8.1... the install ran correctly and the installer did not start early nor did any installs run at the same time. I did still get the shutdown string problem but I will need to run numerous integration's with the newest WinToolKIt versions before I can be sure about the whole shutdown command issue

Lego... just wondering if your latest tests versions addressed this by any chance?

Unfortunately some of the RunOnce installer got cuorrupted so got to do a lot of work to fix it. SVN didn't work properly

That's a drag but I understand so thanks... I am using other features

I'm coding it now. Since RunOnce is .NET 4, i get a chance to use the new parallel threading code

Is it working now?

Yes with /q /norestart
