TAP Driver / TAP-Windows Adapter Issues

OpenVPN on Windows requires a virtual network adapter called the TAP-Windows driver. If OpenVPN gives you an error about a missing or broken TAP adapter, this guide will fix it.

Note: VPNUK Software v1.2.2 installs its own TAP adapter automatically. Only use this guide if you're using standalone OpenVPN. If you use VPNUK Software, reinstalling it will fix TAP issues automatically.

Fix 1: Reinstall the TAP Driver via OpenVPN

Open the Start menu and search for OpenVPN
Right-click OpenVPN GUI and select Run as Administrator
If OpenVPN is already installed, go to Control Panel → Programs → Uninstall a program
Uninstall OpenVPN completely
Download the latest OpenVPN installer from openvpn.net
During installation, ensure TAP Virtual Ethernet Adapter is ticked
Complete the installation and try connecting again

Fix 2: Add a TAP Adapter Manually

Open Device Manager (right-click Start → Device Manager)
Click Action → Add Legacy Hardware
Select Install the hardware that I manually select from a list
Choose Network adapters
Select TAP-Windows Provider V9 from the list
Complete the wizard and restart your computer

Fix 3: Use VPNUK Software Instead

The easiest solution is to switch to the VPNUK Software v1.2.2. It includes its own TAP adapter, manages it automatically, and avoids all TAP driver conflicts.
