FileInUse dialog not showing everything

[HLoEpicor]

Deliberately getting couple of  executables of my application running and try to install a newer version.  FileInUse dialog comes up as expected but only showing 1 of the items (the Windows Service) and not the desktop application.

I have checked this registry key as suggested by other posts: HKEY_CURRENT_USER\Software\Microsoft\RestartManager\Session0000\RegFiles0000

It listed the following files, all are part of my application installed. Only the 2nd last item "EBusinessService.exe" shows up in FileInUse dialog. I expect the "BisTrack.exe" to show up also but it doesn't. If I pick automatic close the applications will be close, but the user installing deserves to see what getting shut down.
