You need camera raw 8.3, which added support for the Canon S120. See
New Camera Support in Camera Raw 8.3
Many thanks for your advice about download raw plug in for my canon camera S120.
However even when I download the Camera Raw version 8.3 it still does not work.
I also noticed that in the adobe download information it seems that the version for canon S120 is preliminary and it is for CS6 and CC.
There is no mention that the version 8.3 if for CS5
Would greatly appreciate if you could help
Warmest regards and merry Christmas
Right, ACR 8.3 is for cs6 and cc; it will not work as a plugin update in CS5. You should download the 8.3 DNG converter stand alone program from
then use it to convert folders of your new S120 cr2 raw files to folders of dng files, which can be processed in your cs5 by acr 6.7 (latest cs5 release).
