The reason I asked is that I worked on this bug <http://wixtoolset.org/issues/4592/> , for Wix 3.10, which is not the same scenario that you observed, but may be related. The pull request was accepted last week, and I don't know if there has been a build of wix 3.10 with this change yet.
I also had issues with a tray app, particularly when it was started by a service. Our product includes both desktop clients and services, any of which may launch the tray app, so there may be multiple instances of the tray app running. Our tray app originally did not have any message pump (which is needed for RestartManager or ClseApplication) so the dev added the message pump in a hidden window. The wix implementation prior to integrating 4592 in 3.10 is that when trying to register a process name (the name of the tray app) with RestartManager, it tries to open each instance of the process. When the tray app was launched by the service, it is running in a different user context than the msi thread related to RestartManager CAs and the attempt to open the process object failed causing the whole setup to fail and rollback. The wix-dev folks advised me, and I implemented a change to 'try' and add a permission to the CA thread to allow a process in another user's context to be opened, however if the installer is not elevated, then we cannot do that. So in that case the new implementation is to skip registering that instance of that named process, post a warning in the log (not error), and continue the setup. In those cases my mba detects if a reboot is needed and prompts for a reboot. I understand the RestartManager in general tries to avoid reboots, but does not guarantee that it won't still signal for a reboot. So the change was to treat a failure to register a named process as a 'we tried', but do not fail. It sounds like this is not the situation you have, but maybe this information will be helpful in some way.
