How to access and play the game

I have downloaded the new FS2020 on a new Lenovo laptop. I can't open and play the game.
All suggestions are welcome. I also want to say i'm disappointed that Microsoft hasn't given
any information informing buyers what is required to access flight sim 2020. Have I paid for
something I can't use on a brand new computer? I'm certain there are other buyers facing
the same dilemma.
