[wix-users] RestartResource is not stopping the application

[Wheeler, Blaine (DSHS/DCS)]

We have an applicaton installed per-machine, Invoked by the logged in user that runs in the system tray.  It appears to be registering itself with the RestartManager when it starts up.

On upgrade I want the installer to stop the app, apply the update and then restart it.  The app does not get closed by RestartManager although it from the installer log it looks the RestartManager tries.  When I watch the exe in the Task Manager I do not see it stopping.

Am I missing a property or should I try scheduling the step differently?

This is the only line I have inserted in the wxs
<util:RestartResource Path="[INSTALLDIR]" ProcessName="$(var.exeName)" />


The log shows thrse steps when RestartResources kicks off
