Hi Tina, welcome to the forum!

Simple questions, simple answers. :slight_smile:

  1. You can choose any link you want (US or CZ) - both will work OK (and most likely will be able to send data faster than your connection speed).
  2. You can save it to any location, or you can directly run (Open) the file when asked what to do (Open, Save As, etc)…

Enjoy your copy of avast!
