If you try to install the Camera Codec pack for Windows 7 on Windows 8, you get an error:
This version of the Microsoft Camera Codec Pack is not compatible with Windows 8 or Windows Server 2012. You can get the codec pack through Windows Update on Windows 8.
However, I cannot see anywhere on Windows update that would suggest I can download this, even as an optional update? Is it just the case that it is not yet live, as everything filters through the RTM process, or is it hidden away as something else?
