Cara Atasi OpenVPN - All Tap-Windows Adapters on This System Are Currently in Use di Windows 7

Ceritanya mau coba OpenVPN di Windows 7, ketika menjalankan salah satu list config yang ada tiba-tiba muncul pesan “connecting to tcp-blablabla has failed” akun OpenVPN gagal dihubungkan dan baca log di GUInya ada pesan error “All Tap-Windows Adapters on This System Are Currently in Use”. Kemudian cek Tap adapternya di “Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings” ternyata kosong tidak ikut dibuat saat proses instal OpenVPN.
