WhatsApp on ARM: No Connection on Windows? Ultimate Fix 2025
TL;DR
✅ ARM-based devices like the Surface Pro X have limited compatibility with some Windows apps.
✅ WhatsApp Desktop can break due to emulation issues — always use the native ARM64 version.
✅ Network, firewall, VPN, or browser settings may also cause problems.
✅ Real user feedback confirms that the native installer resolves the problem for most.
Having trouble using WhatsApp on your ARM-based Windows device? You’re not alone. With more Windows laptops and tablets running on ARM processors (like the Microsoft Surface Pro X or Surface Pro 11), users are encountering connection issues — especially when trying to link WhatsApp Desktop or Web.
Here’s the definitive guide to fixing WhatsApp connectivity issues on ARM Windows systems, based on real-world fixes and expert insights.
Quick Summary of Common Issue
| Problem | Cause | Device Impact |
|---|---|---|
| WhatsApp Desktop fails to link | Incompatibility with ARM64 or x64 emulation | Surface Pro X, Surface Pro 9 ARM |
| “Unable to connect” error | Firewall, VPNs, or missing dependencies | All ARM-based Windows |
| WhatsApp Web times out | Edge/Chrome WebSocket issues | All Windows versions |
| QR code doesn’t load | Proxy or network conflict | Work and school networks |
What Is ARM and Why It Affects WhatsApp?
ARM (Advanced RISC Machine) processors are designed for power efficiency, not raw performance. They’re commonly found in smartphones and some Windows devices like:
- Surface Pro X
- Surface Pro 11
- Samsung Galaxy Book Go
- Lenovo Flex 5G
WhatsApp for Windows is optimized for x64 or x86 architectures, and while Microsoft has made huge strides with x64 emulation in Windows 11, many apps still don’t behave the same way.
Fix 1: Use the Native ARM64 Version of WhatsApp Desktop
WhatsApp now provides native ARM64 builds on their official website — but not all download buttons serve the correct version. Here’s how to check:
- Go to WhatsApp.com/download
- Scroll down and choose “Windows ARM64”
- Install it, then restart your device
Why this works: Emulated x64 apps often fail at network-level functions like WebSocket handshakes, which WhatsApp uses.
Fix 2: Adjust Your Network & Firewall Settings
Step-by-Step:
- Open Windows Defender Firewall Settings
- Click on “Allow an app through Firewall”
- Ensure WhatsApp.exe has access to Private & Public networks
- Check for open ports 443 and 5222 (used by WhatsApp)
Bonus Tip:
- Disable any VPN or Proxy temporarily
- Restart your router to refresh DNS and connection rules
Fix 3: Use WhatsApp Web in Compatibility Mode
For users who only need to use WhatsApp Web:
- Use Google Chrome or Edge (ARM versions preferred)
- Visit web.whatsapp.com
- If the QR code fails to load, try opening the browser in InPrivate/Incognito mode
✅ Pro Tip: Add WhatsApp Web as a standalone app in Edge:
- Click “…” → “Apps” → “Install This Site as an App”
Fix 4: Run Compatibility Troubleshooter
- Right-click on
WhatsApp.exe - Click Properties > Compatibility
- Run Compatibility Troubleshooter
- Choose “Try Recommended Settings”
This will let Windows attempt to optimize the runtime for your ARM environment.
Fix 5: Reinstall WhatsApp with Clean Cache
- Uninstall WhatsApp from Windows
- Press
Windows + R, typeregedit - Navigate to:
HKEY_CURRENT_USER\Software\WhatsApp
- Delete the WhatsApp folder
- Reinstall from ARM-specific installer here
