Install them here (Create the Settings folder if you don't have it):
that's been my issue! that darn settings folder never showed up for me.
so you are saying I can just create it for myself? then any new presets and things I purchase I can just put right in there?
when I tried to do it right from ACR it showed the settings folder... that's the confusing part.
If the folder isn't in the path above then yes, you can create it, although launching Bridge or Camera Raw via Photoshop should automatically generate the folder and the index.dat file for you. Keep in mind this is in the "User" Library folder and not the "system level" Library folder. That may be what is causing the confusion.
