This is the installer for Mesa on Windows ARM64. This installer contains
binaries for ARM64, x64, and x86, so it should work with all applications that
can be run/emulated on Windows ARM64.

There are two installers here:

setup-mesa-dozen - Installs the Mesa Dozen (Vulkan-on-D3D12) driver

setup-mesa-gl - Installs the Mesa D3D12 Gallium driver (OpenGLOn12)

The Dozen installer also includes builds of the Vulkan loader for each
architecutre and appends them to the PATH environment variable. But be aware
that some applications expect that vulkan-1.dll is only present in
C:\Windows\System32 and will not find it in PATH. This is a little tricky
because ARM64 and x64 applications use the same System32 directory (while x86
uses SysWOW64). This prevents us from installing the loader system-wide,
because if we install the x64 loader then ARM64 applications will break, and
vice versa. I haven't found a good solution for that problem yet. If anyone has
ideas, please let me know.

The GL installer sets itself as the default OpenGL driver when the native
graphics driver lacks OpenGL support. Note that this is incompatible with
Microsoft's OpenGL and OpenCL Compatibility Pack[1], which provides similar
functionality.
