In general, Arnold is going to work on pretty much any 64-bit system where Houdini, Maya, Cinema 4D, or Softimage works. However, there are some minimum OS requirements:
- OSX 8 or later (as of Arnold 188.8.131.52)
- Windows 7 or later (as of Arnold 4.2.3)
- Linux with at least glibc 2.12 and libstdc++ 3.4.13 (gcc 4.4.7). This is equivalent to RHEL/CentOS 6 (as of Arnold 4.2.6)
- CPUs need to support the SSE4.1 instruction set (as of Arnold 184.108.40.206)
Other than that, Arnold works on Intel and AMD processors, and has no graphic card or GPU requirements, since Arnold is a CPU-based renderer.

As of Arnold 220.127.116.11, the minimum Windows version is Windows 7. We no longer support Windows versions before Windows 7 and Windows Server 2008 R2.
This applies to all plug-ins (such a MtoA 1.2.02 and later, or SItoA 3.4 and later) that use Arnold 18.104.22.168 or later.
If you try to load an Arnold plugin on an unsupported Windows, you’ll get an error (something like “The specified procedure could not be found”).
On Vista with Arnold 22.214.171.124 or later, kick -nodes gives you a more specific error:
"kick.exe - Entry Point Not Found"
"The procedure entry point SetThreadGroupAffinity could not be located in the dynamic link library KERNEL32.dll."
