Just reinstalled Qt from scratch.
I see selecting open at finish now works.

After dismissing the prompt to setup Android for later, I see a message in General messages
concerning Android global variable. At the point of dismissing the message for "later"
you might want to ask if you want to disable Android support as an option. Right now
I don't want to use probably 80% of your download. I am just beginning. Now some
people who are experienced developers know exactly what they want.

How about an install option for new beginners that only installs the "basic" tool. Give
them the option to at least choose.
