We're working on this

+1 don't make me program myself i again :(

Been trying to get the x64 one to install (as the installer even saws it worked fine in the x64 translation layer).

Installing via WinGet or using the PowerShell commands listed on the site either don't install Claude or when it is installed, crashes immediately. I submitted a ticket with the AI Support Bot on the Claude web.

Currently only working method is to use npm. When running claude install like the npm version says to, this error comes up:

> claude install --force

✘ Installation failed

Platform win32-arm64 not found in manifest for version 2.1.17


Try running with --force to override checks

+1. For me, it installs but segfault frequently and not useable.

The npm version works, but there's a strong push to use native installer everywhere. Please consider fix this first then do the push.

+1 for me. I'm adding my data point as a non-developer Windows ARM user:

Hardware:

• ASUS Zenbook A14 (UX3407QA)
• Snapdragon X X1-26-100 (8-core, 30MB cache)
• 32GB LPDDR5X RAM
• Windows 11 Home

Use case: I'm an attorney using Claude Code for document drafting, email workflows, and task automation — not software development. Max plan subscriber.

Current status:

• Native installer fails with "Platform win32-arm64 not found in manifest"
• npm workaround (npm install -g @anthropic-ai/claude-code) works reliably
• Concerned about npm deprecation as the only working path

Why ARM: Battery life and portability are critical for court appearances and client meetings. This machine gets 20+ hours and weighs 1.2kg.

Happy to test builds or provide logs if that helps. Thanks for working on this.

Hey @AaronHallAttorney

Cool that an attorney uses AI :)
For a workaround if you are not aware claude code will work in WSL (emulation).

1. Open powershell as admin
2. WSL --install
3. Then open ubuntu:

1. Proceed to download claude code how you would normally.

It will work now for you.

@avinther Thanks for the tip. WSL is a solid option.

For others landing here, there's also a native Windows workaround that avoids emulation:

Install Node.js (which has ARM64 support)

winget install OpenJS.NodeJS.LTS

Install Claude Code via npm

npm install -g @anthropic-ai/claude-code

This runs Claude Code natively on Windows ARM64 through Node.js rather than Bun.

Why you might prefer npm over WSL:

• No emulation layer — runs native ARM64
• Simpler setup (no Linux subsystem to maintain)
• Better integration with Windows paths and Google Drive
• WSL + Google Drive has known friction (mount race conditions, slower I/O)

The npm install method is marked "deprecated" in the docs, but it works reliably and will likely continue working until Bun adds ARM64 support (tracked in https://github.com/oven-sh/bun/issues/5814 since April 2024).

The npm method is literally the only way it works on Windows on multiple machines for me.

Confirming this issue on Windows 11 ARM64 in Parallels Desktop (Mac host)

Environment:

• Host: MacBook Air M4
• VM: Windows 11 ARM64 via Parallels Desktop
• Claude Code: Native installer (latest)
• Error: Segmentation fault immediately when running claude

Observations:

• claude --version and claude --help work fine
• Any actual execution (e.g., claude doctor, claude -p "test") crashes with segfault
• Windows Update KB5074109 is installed (cannot uninstall on most systems)

Working workaround:

npm install -g @anthropic-ai/claude-code

The npm installation works without issues, confirming this is specific to the native binary + x64 emulation on ARM64.

Request: A native win32-arm64 binary would resolve this permanently. With the growing adoption of ARM64 Windows devices (Surface Pro, Snapdragon X Elite laptops, Parallels VMs on Apple Silicon), native ARM64 support is increasingly important.

+1 this is really frustrating especially as they are adding native binary only features like opus 4.6 fast mode.

We're working on this, and will have an update soon! :)

Builds for Windows ARM64 are now available as of 2.1.41! Install using the install.ps1 / install.cmd flows in https://code.claude.com/docs/en/setup#installation.

We expect to start getting future builds into winget sometime next week.

ARM64 builds are available in winget starting with 2.1.42 - winget install Anthropic.ClaudeCode
