64-bit machines run 32-bit software just fine.

Tell that Apple and Android. I have 32 bit native software which can't run on modern devices at all.

I'm sorry to hear that. Could it be ARM related?

		Apple dropped 32 bit support in specific OS version with no way to run it anymore sans downgrading the OS - so it's not hardware restriction

		It's just to reduce the maintenance burden of backwards compatibility.
