need raw update for canon 7d mark II

See that post from today:

Can Camera Raw 8.6 as part of Elements 13 support Canon 7 D Mark Two?

You'll have to wait for that.

In the meantime, use the DPP software provided with your Camera by Canon.

I suspect it won't be long before a new ACR version is available for PSE13 or a new Adobe DNGconverter is issued if you have older Elements versions.

FAQ: Will Photoshop Elements work with my camera, or Why won't my raw files open?
