I installed it on my Steam Deck using the Discover app "Bottles" to run the EXE. Since Bottles is required to run it, I haven't been able to get it to work in game mode but it works fine via desktop mode.
I'm on my Windows PC now so I was able to pull the direct file link to the EXE installer, here you go:
