This error usually indicates that somehow the network adapter (TAP) that is required by the OpenVPN application has been disabled on the system.
To resolve this issue, please follow the steps below:
Go to Control Panel > Network and Sharing Center.
Click on ‘Change Adapter Settings‘ and you will see a list of all your configured network
Find the one that is called ‘Local Area Connection XX or Ethernet XX (XX denoting a number) and that has a description of ‘TAP-Win32 Adapter V9‘.
If it’s disabled, right click on it and choose Enable.
If you can’t see a network adapter matching that description then it could have been deleted and so you will need to add it back again.
To do so, please follow through the steps below:
1) Go to Start – All Programs – Tap-Windows (Windows XP, Vista & 7) or press Windows + Q, and look for Add a New Tap (Windows 8, 8.1, & 10)
2) Right click on Add a New Tap Virtual Ethernet Adapter and select Run as Administrator. If you do not have the Run as Administrator option (Windows 8, 8.1 & 10), select Open File Location, right click on Add a New Tap Virtual Ethernet Adapter and select Run as Administrator.
3) Follow through the instructions and you’ll end up with the following screen:
4) Once you’re greeted with the screen above, press any key on your keyboard to continue and give the VPN another try.
