I have an app (MiKTeX) that is installed by force running (once) its
setup.exe. This app is associated to a number of workstations. Setup
takes approx. 10 or more minutes to install the app.

When we rebuild a machine, ziswin starts and goes about it's machine
re-naming. Shortly thereafter, the installer begins installing MiKTeX
(this somehwat surprised me). When ziswin finishes, but before the
installer completes, the machine reboots, leaving an incomplete
installation. The installer does not restart due to run once being set.

If just associated to a workstation (that was not just re-imaged) the
installer works flawlessly.

Anybody have any tricks to delay the launch/installation of apps until
after ziswin is finished and the machine reboots?
