Thanks to all for your response. I have CS6 and am not sure of what ACR I had because in trying to update it, it has disappeared.
I think I've isolated the problem. Basically, I'm working with an old OS X on my iMAC (Snow Leopard), that will not allow me to upgrade my ACR to vs 8.7.
I'm working on the upgrade to OS X, but interestingly (e.g. frustrating) Apple does not have that as a download, you have to purchase it and the EMAIL you the update, which takes up to 3 business days. As I started this on Friday, I'm still waiting for my upgrade.
So, my enthusiasm for processing my 7D II images will have to be subdued for awhile.
I hope I don't have another issue, as I converted the 7D images to jpg, and PS CS6 does not recognize them either.....
