So I just bought and downloaded The Witcher 3 Goty and I've been trying to add it to steam as a non-steam game but when the window opens up I can't see the witcher 3 on my desktop nor my folder where I set it to download. Idk why it's not showing up it is a .exe file so it should be showing. Got any suggestion ?

As far as I know you have to install the game first before you can add it as a non-steam game.
