When I tried to download ASW files/photos from my new Sony A7R II camera to Lightroom newly upgraded to 6, I couldn't, and objection was "The files are not recognized by the raw format support in Lightroom. (6)" How does this problem get solved?
Are you on 6.0 or 6.1.1? I checked the supported camera list and the Sony A7R II is listed for 6.1.1 and up. More info here:
