The SurrenderingToMyCrush-32 version is the 32-bit version, most likely the other one will work on your PC. As for the saves, they are saved automatically, even if you delete the game, the games are saved locally in another directory.
It has to do with your operating system. There are two types, 32-bit and 64-bit. Depending on your version (as I said, it's usually 64-bit), you should open the correct one. If one doesn't work for you, simply open the other 😊
