TAP adapter detection

[Greg Toombs]

I'm fairly sure that the TAP driver is installed correctly:

"C:\Program Files (x86)\OpenVPN Technologies\OpenVPN
Client\core\openvpn" --show-adapters
Available TAP-WIN32 adapters [name, GUID]:
'TAP Adapter' {443C9063-3FD4-498A-8D5A-A7578835D871}

But then when I run openconnect, it seems to work up to here:

...
Connected to HTTPS on xxxxxx.com
Please enter your username and password.
Username:xxxxxx
Password:xxxxxx
POST https://xxxxxx.com/+webvpn+/index.html
Got CONNECT response: HTTP/1.1 200 OK
CSTP connected. DPD 30, Keepalive 20
Microsoft (R) Windows Script Host Version 5.8

No Windows-TAP adapters found. Is the driver installed?
Set up tun device failed

Any idea what's up?
