File appears to be from a camera model not supported [Unable to open Canon 6D II Raw files in PSE 12]

I just bought a new camera, a Canon 6D Mark II.  When I attempt to open a RAW image in Photoshop, I receive the following error message; File appears to be from a camera model which is not supported by the installed version of camera RAW.

I am using Elements 12.  My new camera and 100mm macro lens cost me an arm and a leg, please don't tell me I now need to upgrade my version of Photoshop.  Is there some setting I need to change, or something I can download in order to open my RAW images?

Thank you,

Steven
