The app is a wine bottle wrapped as a macOS app. You can open it like a folder with a right-click and inside it is a Wine configuration tool. Launch it, maybe something needs to be adjusted to your macOS version. I am still running 10.14 Mojave as I need 32bit support for some apps I am using.
i spent a little time fiddling about with the wine wrapper thing and it still didn't work no matter what i did, i think it might be my macos version causing the problem, sorry for wasting your time :/
