| Client Version | Driver Version | Supported Windows OS | Major Architectural Changes |

2. Why You Should Upgrade from v4.6.9 to v6.3 on Windows 10 & 11
Many older tutorials on YouTube and Reddit still reference wo_mic_client_4.6.9.exe and the separate wo_mic_driver_setup.exe. Installing v4.6.9 on a modern Windows 10 or Windows 11 PC causes three avoidable problems:
- 1. Code 52 Driver Signature Block under UEFI Secure Boot: Legacy v4.x drivers lack modern Windows 10/11 kernel catalog signatures and are blocked by Windows Device Manager with Code 52 (Windows cannot verify the digital signature). Version 6.3 includes the signed driver (see our Virtual Driver Guide).
- 2. Protocol Mismatch with Current Android v5.3 & iOS v1.4 Apps: When your phone auto-updates the WO Mic Android app or iPhone app, connecting to an ancient v4.6.9 PC client results in a "Protocol version mismatch" error.
- 3. Missing Auto-Reconnect & 48 kHz Audio: Version 6.3 automatically restores dropped Wi-Fi/USB sessions and runs at native 48 kHz for Discord and OBS Studio.
3. How to Cleanly Upgrade from an Old WO Mic Version to v6.3
- Close the old WO Mic Client completely from the Windows system tray.
- Open Device Manager → Sound, video and game controllers, right-click WO Mic Device, choose Uninstall device, and check Attempt to remove the driver for this device.
- Reboot your PC, install vc_redist.x86.exe if needed, and run the WO Mic v6.3 installer as Administrator. For safety verification details, read our Is WO Mic Safe? Audit.
Frequently Asked Questions
Does WO Mic v6.3 still work on Windows 7 and Windows 8.1?
Yes! The v6.3 installer includes driver files for Windows 7, Windows 8/8.1, Windows 10, and Windows 11 (both 32-bit and 64-bit editions).
Why do I get 'Version mismatch between client and app' when connecting?
Your PC is running an outdated v4.x client while your phone is running the v5.x/v6.x mobile app. Upgrade your PC client to v6.3 and the handshake error disappears immediately.
Where can I download the legacy Linux version of WO Mic?
Official Linux development ended after the x86_64 AppImage release, which remains available with full ALSA snd-aloop instructions on our WO Mic for Linux page.
Do I need to uninstall the old version before installing v6.3?
Yes, we recommend uninstalling any v4.x driver from Device Manager first so Windows 10/11 replaces the old unsigned .sys file with the signed v6.3 driver.
