Why can't I download UE4?

I want to download UE4, but it says “Unreal Engine 4 require a 64 bit operating system. You’ll need to update your system to install UE4.”

I double checked my device specifications and it definitely says it runs on a 64 bit system. I thought maybe because it uses an ARM-based processor?
Can anyone confirm?

So what CPU is this exactly? What is the device you’re trying to run the engine on? A laptop with a Snapdragon perhaps? Or the M1?
