I can't install the program Unreal Engine on my MacOS

I have MacBook Pro (Retina, Mid 2012) Catalina, version 10.15.7
I cannot update my computer to the required version.
I was able to download the program, but when I try to open it, it says “System requirements do not meet.”

Maybe someone had same problem?
Please give some advice so that the program will work on the laptop and not corrupt existing files and data.
