Do you open UI by default when you type [ApplicationName].exe?

It is always a good practice to have UI opened when specifying \[ApplicationName].exe from command line. If the GUI is not done, show a messagebox "GUI coming...".

Note: If you prefer for not putting UI as the default, it should have be at least "/GUI" as the argument. Do not use "/i", because too many command lines are using “/i” already.
