Unable to import RAW files in CS6 from a Sony A7iii

Hi,

As per the title I am unable to import Raw files from my A7iii into photoshop. I keep getting this error message: 

According to this link I require (for the A7iii) camera Raw version 10.3 or higher, which I have tried downloading and installing multiple times with multiple versions and when I reopen photoshop and try opening the RAW file it again comes up with this error.

Anyone know how to fix this?

Also just a warning im not tht tech savvy so could easily be doing something simple wrong!!

Thanks 

Will
