Did you edit these images somewhere prior to editing them in Camera Raw as Camera Raw 6.7 does not support Process Version 2012 and as per the error, the settings used on those images were of Process Version 2012 ?
Do you get this error message only while working with those presets?
I haven't edited the images elsewhere. I get that message with all presets that I have purchased. The error message says those settings "USE process 2012" not the settings USED. I believe though, that you answered my question? If Camera Raw 6.7 doesn't support process 2012 and 7.0 does, then I will have to do another upgrade. However, that means I need at least CS6 to run it. If I upgrade to CS6, won't I have to go to CC?
Yes, it means you have to upgrade.
CS6 is available as a standalone version so, you would not have to go for CC if you are not willing to.
