Solution 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.

Solution 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!

What i did before i post this?
- Removing the TAP-Win32 Adapter OAS
- Reinstall openvpn
- Reinstall openvpn gui
I have the problem on two computers. Why?

My System:
- Windows 7 Professional 64-Bit
- Normal Network Interface
- VirtualBox Network Interface
- TAP-Win32 Adapter OAS
All legal. All up-to-date (newest, stable version).

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

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

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.

@BradlySpicer Worked for me on Windows 8.1, too.

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)
