Alright something weird is going on with this one. There are two Syberia buttons to claim the game on the store page. Don’t click on the first/top Syberia giveaway button on the steam store page like I did. The game won’t show up on your account even if it says that you own it in your licenses page.
Instead click on the second/bottom syberia giveaway button, then it will show up properly in your account and library.
Just click “Install” and you’re good to go.
