Re: Forced legacy edition on 64 bit ARM processor computer why? TS4
You can see minimum requirements here https://answers.ea.com/t5/Technical-Issues-PC/READ-FIRST-Make-sure-you-meet-minimum-requirements-PC-Mac/m-p/6420780#M102196 They are also listed on the purchase page. ARM processors are not supported.
Edit:
Here is a bit more on what wont work on ARM.
For starters, only ARM64 drivers are supported. While Windows 10 on ARM will be able to emulate x86 apps, you'll need ARM drivers to make them work. For most modern hardware and peripherals, this isn't an issue. But if you have a favorite mouse from 1994 that you still use, that likely won't work.
Additionally, x64 apps (the 64-bit version of apps coded for Intel'x x86 platform) won't work.
Some games won't work. If they use a version of OpenGL later than 1.1 or require hardware-accelerated OpenGL, they won't run. In addition, games that need anti-cheating drivers won't work on Windows 10 on ARM. This probably isn't much of an issue, as the first systems don't have the discrete GPUs you'll need to play games.
Some apps just won't run, either. Specifically, anything that modifies Windows 10, including assistive technologies and cloud storage apps like Dropbox. These will need to be recompiled for Windows 10 on ARM, so it may be awhile until these apps are available.
Perhaps the funniest of the limitations is apps that were originally designed for Windows 10 Mobile may work incorrectly. Considering that Windows 10 Mobile only runs on ARM processors, this incompatibility is a little ironic.
Finally, Windows 10 on ARM won't support the Windows Hypervisor Platform, so you won't be able to run virtual machines on Hyper-V.
