It is a few questions that we know should be handled by a post-installer configuration utility. But that's not important at this point. I can't change that now. But rest assured, we'll address it in the next major release.
Our application runs as a service and doesn't require user input. But your question as a sentence is funny, because zillions of programs require user input (notepad?) :)
Our installer needs to know where a license file is, and it shouldn't install without this license. I set it up to allow user to browse for that license. In quiet mode this dialog does not appear, which is appropriate for quiet mode, obviously.
And the 'developers' (me and a 2 other people) are very tired of having to do this every time. But that aint gonna change soon.
I tried to 'fake out' the bootstrapper by setting the quiet install options in the config file for my msi to nothing, but that did not seem to have an effect.
We'll just document that we don't support silent installs in the install doc, until we can properly exploit this feature and get our config stuff into a separate application.
