What is the difference in launching the shortcut in configure software phase and installation phase in App-V?
In App-V 5.x the launch is there to manage first use tasks, it's a step added that wasn't in 4.x.to clarify the need to configure licensing and other items on first launch. The FB stuff is now in the customize phase, in the streaming options.
yep, not much really.
There is no real difference as dunnpy mentioned, but it is handy to have a distinction between the install, then the config. I normally run the app from the Startmenu shortcuts during the 'install phase' and do all the config I want rather than in the App-v dialogue 'run each program...' mainly because the App-V GUI stress's me out.
One of the best things Microsoft did was add that tick box in your first image..
'I am finished installing...'
