Just got steam to play an old game from my childhood on my M1 Macbook, but its not opening for me.

I get the error "Missing game esecutable-/Users/(my name)/Library/Application Support/Steam/steamapps/common/Ignition/DOSBox/dosbox.app/Contents/MacO".

My cousin tested it out on his M1 Macbook and its working fine for him. What do i have to do for it to work? I tried looking online but nothing seems to be working.
