Originally assigned to: @dhiltgen on GitHub.

I tried to run it on a Windows on ARM device and the installer refused to exectue.

Is there any plan for the native Windows on ARM support? Or is it possible to remove the architecture checking and make the x86 version work on ARM devices?

@dhiltgen AFAIK windows has pretty good emulation support for running amd64 apps on arm64 windows – it might be worth removing this hard check as a starting point

PR #3111 will at least allow us to install, and run under emulation. Performance isn't good, so I'm not going to close this ticket until we actually build a native ARM binary.

@dhiltgen How can I be of help? I have a Windows on ARM laptop (the Surface Pro 9 ARM64 flavor).

I have a few questions. I see the instructions to build for Windows (on x64) in https://github.com/ollama/ollama/blob/main/docs/development.md#windows

Those steps look like Powershell (or did I get that wrong?)

Also, any chance this will be NPU accelerated (my laptop has one, the Hexagon, by Qualcomm) ?

I was able to compile it locally for ARM64. I'll try to create a PR soon. I'm glad that NEON and Armv8.2 extensions are automatically enabled without extra CMake switches when ARM64 is detected
