Hello, here's the steps to downloading the game:-
1. First of all you need to extract the zip file and after you're done with that this is the folder you'll see.
2. After That just open this folder and run the .exe file named "237.exe"
If you're still not able to find the .exe file, I would suggest re-downloading the game, that will definitely solve the issue.
I hope this was helpful, if you encounter any other issue let me know.
