Can you play the modded version of Hard Time III on Steam Deck?

I am new to Steam Deck and recently got Hard Time III and attempted to run the mod version on Steam Deck. It wanted me to download and install a .exe file when I tried to run the game. I was able to download the file but when I try to open it, the Steam Deck doesn’t know what app to use and sadly neither do I. I am including a photo of the pop-up that occurs whenever I try to run the mode version on my Steam Deck.

Bonus points to anyone who can also tell me how to get the game to play full screen on the Steam Deck. For some reason it wants to play in a 4:3 format (like the iPad version) but I don’t seem to see any game settings that allow for different screen formats.

Any help or information would be amazing!
