I haven't needed to do this for a while, but... I believe that the latest release of Adobe DNG Converter (currently 10.0, released Oct 18 2017) includes up-to-date lens/camera profiles. You can use that to convert your camera's raw files (CRW, NEF, or whatever) to DNG form, and that DNG can then be opened by earlier versions of Adobe Camera Raw. (I could be wrong, but that's how I remember it.)
But you can’t get the latest Adobe RAW to download to Photoshop CS6. It needs to be a recent version. I go through this all the time since my Lightroom has a newer Adobe RAW than my Photoshop. I’ve never tried to download it independently but that would be very useful if it works. I’ll check it out. Thanks.
