Currently, the only processor architecture supported by MH MW is x86-64. To my understanding, aarch64 processors can emulate x86-64 but supporting them natively would improve performance.
To avoid making the user experience more complex, maybe the best way to do this would be to keep the installer as x86-64 only (or add an “advanced downloads” page with the aarch64 installers) and have it detect the architecture and select the multiworld build to install accordingly.
