I have the problem on two computers. Why?

My System:

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), installing "TAP Utils" and then invoking "add a new tap virtual network adapter" (open start menu and just type "TAP" there) – Margenemargent

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. – Delimitate

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. – Penang

had issue in win10 able to solved it : go to TAP-Windows\bin path (Ex:C:\Program Files\TAP-Windows\bin) and run addtap.bat file – Uphroe

Answer 1

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. – Palmar

On Windows 7 I didn't see a disabled connection. I ended up disabling the TAP installer and Re-enabling it. – Cloaca

The issue is off topic indeed - but thanks a bunch - works. – Antwanantwerp

@BradlySpicer Worked for me on Windows 8.1, too. – Eba

Works on windows 10. Wow, what an easy solution! – Sportswoman

Answer 2

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. – Tailstock
