ACR is a plug-in for Photoshop, not a standalone program, so it’s unclear what you mean by default directory. What steps did you do to install it?
Thank you for your support.
I downloaded the CameraRaw 8_6.dmg file and followed the installations prompts.
Hopefully I did not download the wrong program. I use the latest Lightroom version.
LR doesn’t use the ACR plug-in, only Photoshop. What are you trying to do, exactly?
You can download the DNG Converter 8.6 RC and convert your NEFs to DNGs, one folder at a time, then those would import in LR, but otherwise, installing a PS plug-in isn’t going to affect LR.
The DNG Converter is part of the CS6 ACR 8.6 RC set of downloadable files at Adobe Labs, not part of the CC set.
Thank you for you help.
Will give this a try.
