Support for Windows 10 ends in a few months, and you're still using Windows 7? Maybe it's time to switch to at least Linux if your system can't handle Windows 11. Most games nowadays run fine on Linux.
Less than 1% of Steam users are still on a 32-bit OS. It doesn't make sense to release a 32-bit version (which may require additional work and support for long time) just for a few players. Maybe it's time for you to switch to 64-bit (like the other 99% already have).
