Re: How do I fix "Launch Error Unsupported host machine architecture. (ARM64)?"

@mb_lbj23 I get this message on pretty much any game using Epic's Unreal game engine. It's very frustrating they put in an architecture check which basically invalidates the x64 emulation in Windows 11. I haven't found a way to get these games to ignore the check. There are plenty of other games that will run that are Intel 64-bit. I'm on a Surface Pro X so it's definitely not a M1 via Parallels issue.

@domboy Thank you for the input. I wonder if that is a limitation of Unreal, but I would be very surprised if it actually is.

No, I unfortunately have not. The check is still in place, and no amount of fiddling with the emulation settings results in being able to hide the architecture from being detected. I was hoping the new Unreal engine would fix this, but EPIC has not seen fit to allow ARM CPUs to play games based on their engine. Really annoying. Compounding the problem is some of the games I've tried use Battleye, and that also crashes. Their support doesn't even respond.

@VanillaWondr Its not limitation of Unreal as it does support Arm64.

Also Apex is not an Unreal game anyway, its Valve Source.
