Even if you get the drivers to work on a modern system, Windows updates have a habit of "upgrading" them, breaking the connection and forcing you to repeat the entire process. For a more stable, permanent solution, many experienced users recommend using a virtual machine (such as VMware or VirtualBox) running Windows 7 (32-bit) exclusively for your Opcom. The interface is then passed through the VM via USB.
