Windows - "Multiple TAP-Windows adapters"

Error: When using --tun-ipv6, if you have more than one TAP-Windows adapter, you must also specify --dev-node
Exiting due to fatal error

That one can happen when you have multiple TAP-Windows adapters, most of the time because of another software using TAP. To fix it, open a command prompt (Shift+Right click) in your OpenVPN directory (where openvpn.exe is), and run:

openvpn.exe --show-adapters

This will list your TAP adapters. Then, open your ccrypto.ovpn configuration file with notepad and add this on a new line:

dev-node [name]

Replace [name] by your TAP adapter name.
