I'm not sure about what a console would be able to provide. Granted I am not familiar with using one either. As I understand it, it would show what is happening as the EXE triggers events. Would it show the processes that check to see if there is a switch in force on the command line?
I'm sure there HAS to documentation somewhere. I think that if you have the new viewer configured to auto-update, it is just launching the install process using a silent install switch (I saw it flash by in a command window).
I'll keep looking... Maybe I'll ask on twitter too.
