Solution

**Solution** 1. Download OpenVPN manually: http://openvpn.net/index.php/download/community-downloads.html :) — PatrickB, Feb 15 '13 at 14:44
Alternatively, if you use other software than OpenVPN package you may want to add TAP by hand, by downloading TAP-Windows from OpenVPN package ([link](https://openvpn.net/index.php/open-source/downloads.html)), installing "TAP Utils" and then invoking "add a new tap virtual network adapter" (open start menu and just type "TAP" there) — Marcin Orlowski, Nov 19 '15 at 12:09
You got this error is because there is not enough TAP virtual ethernet adapters in your system. **Here is the solution**: `Startup menu --> All Programs-->TAP-Windows-->Utilities-->Add a new TAP virtual ethernet adapter` . You can create several adapters if you need to connect multiple VPN at the same time. — mainframer, Feb 27 '16 at 04:29
Keep in mind to run any Shortcut from windows menu as "Run as Administrator", otherwise it will fail. Same apply to manual command line, the command prompt/Cygwin, any shell need to be started to run under Administrator rights. — kensai, Oct 20 '16 at 08:47

I found a solution to this. It's bloody witchcraft, but it works.

When you install the client, open Control Panel > Network Connections.

You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).

Right Click it, click Enable.

The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.

Thanks a million! I was tired of not being able to solve this issue. – Zeeshan S. Jun 27 '14 at 22:29

On Windows 7 I didn't see a disabled connection. I ended up disabling the TAP installer and Re-enabling it. – Bradly Spicer Sep 30 '14 at 10:52

The issue is off topic indeed - but thanks a bunch - works. – Olaf Feb 19 '15 at 08:36
@Bradly Spicer, thanks. Exactly what i needed. – Ariel Deil Jul 29 '15 at 13:09
@BradlySpicer Worked for me on Windows 8.1, too. – Perrier Sep 01 '15 at 09:31

It seems to me you are using the wrong version...

TAP-Win32 should not be installed on the 64bit version. Download the right one and try again!

I'm using this version: `Installation Package (Both 32-bit and 64-bit TAP driver included): openvpn-2.0.9-gui-1.0.3-install.exe`. – Edmund Sulzanok Aug 03 '15 at 09:35
