Windows 7 OpenVPN TAP driver unsigned error

I’m having a lot of trouble getting a Windows 7 virtual machine (VM) to connect to a VPN. I’m using a Ubuntu 12.04 host, with a bridged network interface and an OpenVPN client installed. However, when I try to connect to a VPN server using the TAP driver included with OpenVPN, I get the following error:

OpenVPN is an SSL VPN tunneling protocol. It is not as well known as IPSec, but is quickly gaining popularity. One reason for its popularity is that it has fewer configuration issues and that it has native support in more operating systems. (For instance, it is the default VPN protocol for Mac OS X 10.5 “Leopard”, and it is supported natively on iPhone and iPad. It is also available for use by most other *NIX systems, and can be configured in Windows.)

The author of this blog post realized that his VPN connection became unstable after updating to Windows 7. The author seems to be quite angry about this problem. The post describes how to fix the problem with the help of an installation file.

There are many reasons for a failed installation, for example. For example, a faulty driver, an invalid or expired driver signature, or conflicting drivers, to name a few.
