I have a Mac 10.11.4 which is running ACR 9.1.1 on CS6. I needed to update to ACR 9.5.1 because 9.1.1 was not opening my new Nikon D500 NEF files. I downloaded 9.5.1 successfully, ran the installation and it said it was successfully installed. However the old version 9.1.1 continues to be the ACR version opening up which won't open these new D500 files. I installed the new version several times and rebooted several times but 9.5.1 still won't show up, though each time it said it installed successfully. Any help would be much appreciated. I am frustrated to tears to know why this won't open.
Adobe stopped Camera Raw for CS6 at 9.1.1
You need to convert your raws to DNG format with the free DNG Converter.

Thanks for the super fast reply. I've downloaded the converter and got that to work as a work around. Bummed I need to do a work around but thankful I haven't lost my mind. Thank you kindly!!!!
