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 - Windows

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!
