[DOCS] Windows ARM64 support missing from setup requirements and overview download links

Section/Topic

System requirements (setup page) and download links (overview page)

Current Documentation

Overview page (overview.md) only lists Windows x64 for desktop download:

* Windows (x64)

No ARM64 link or mention.

Setup page (setup.md) lists OS requirements without any architecture information:

Operating System: macOS 13.0+ Windows 10 1809+ or Windows Server 2019+ Ubuntu 20.04+ Debian 10+ Alpine Linux 3.19+ * Hardware: 4 GB+ RAM

No mention of which architectures are supported on which OS.

The desktop page (desktop.md) does mention ARM64 as a footnote with a download link and an important caveat: "Local sessions are not available on ARM64 devices, so use remote sessions instead." But this information doesn't appear on the setup or overview pages where users first encounter system requirements.

What's Wrong or Missing?

v2.1.41 added Windows ARM64 (win32-arm64) native binary support, but the documentation coverage is incomplete:

1. Overview page: Missing ARM64 download link — users on ARM64 Windows devices see only the x64 link
2. Setup page: No architecture requirements listed at all — users can't determine if their architecture is supported
3. ARM64 limitation not surfaced early: The desktop.md page notes that local sessions aren't available on ARM64, but this limitation isn't mentioned in setup or overview where users make their installation decision

Suggested Improvement

1. Overview page: Add ARM64 download link alongside x64:

Windows x64 Windows ARM64 (remote sessions only)

1. Setup page: Add architecture information to system requirements:

Architectures: x64 (AMD64): macOS, Windows, Linux * ARM64 (Apple Silicon, Snapdragon): macOS, Windows (desktop app — remote sessions only), Linux

1. Setup page: Add a note in the Windows section about ARM64 limitations.

Impact

Medium - Makes feature difficult to understand

Additional Context

• Native binary added in v2.1.41 (released 2026-02-13)
• Previous issue #20043 requested the ARM64 binary — now that it exists, the docs should reflect it
• The enterprise deployment article (support.claude.com) already lists both x64 and ARM64 MSIX installers, so the end-user docs should match
• macOS ARM64 (Apple Silicon) has been supported since launch and is not called out separately — the Windows ARM64 case is different because of the "remote sessions only" limitation
