Staff1. For /SilentMode: If this argument is specified, TestComplete works in Silent mode, that is, it neither displays dialogs, nor informs you about errors or warnings. The dialogs and messages to be displayed are handled as if you pressed the default button in them. "- I can't tell you exactly what gets suppressed or not. I think it's a fair assumption to say that most everything would be (including those error/warning dialogues). I've also seen that using the /exit argument closes the instance down immediately after the test runs as well.
2. I'd then suggest using /ExportSummary or /ExportLog arguments to achieve this end goal - this way, even in silentmode, you can take a look at your test results whenever you want by finding the files within that specified directory.
3/4. I think the options above address the needs that we dont really need to explore this option.
