I‘m trying to play Dungeon Siege 1 on the Deck. According to ProtonDB - with some adjustments - it should work just fine.

However, when I‘m trying to install the game, the „Install“ button is greyed out and it says „Available On Windows“ next to it. If I tap/click the install button, nothing happens. So the game doesn‘t even download.

I haven’t encountered this with any other games before. I think I had the game installed on the Deck before, it has launch parameters (just res and such) configured for the game. Either something changed or I‘m doing something very wrong and I‘m trying to figure out which it is.

Since the Deck doesn‘t give me an error message and googling the issue didn‘t return anything useful, I have nothing to go by, I‘m hoping someone here can give me a pointer. Thanks!
