Installing it was a bit harder than I would have wanted it to be, however the problem isn’t down to the theme itself. In order to install it, you first need to flash the device with the Artemis USPL which basically opens it up for the installation of any ROMs you want to burn onto it. Unfortunately when I tried installing this, Vista kept messing around and losing connection to the device half way through the process. I finally found a fix for installing the USPL on Vista which involved replacing the USB driver that Vista uses to talk to the device in bootloader mode with a different version. Once I got that sorted out installing WM6 was a doddle.
