This conversation has been merged. Please reference the main conversation: Photoshop: Lightroom 4 requires Camera Raw 7.0

There seems to be an issue with LR4/PsCS5 workflow due to the fact that LR4 uses ACR 7, which is not available for CS5. What this means is that you've released a major product from your suite that introduces a significant glitch with workflow with the latest available version of another product in your suite, and you can't spin that as anything other than a glaring flaw. Opening in Lightroom is not a viable option, as that creates a potentially unwanted file immediately. Obviously, waiting for CS6 is not a viable option, especially since an upgrade will presumably cost about $200 and we don't even know when it will be available... Several users have been told to download ACR 6.7, but this does not correct all reported issues and directing your users to utilize a version of camera raw that's still in beta is not acceptable. No matter how you spin this, you've released a major component of your suite that is not compatible with the latest version of another major component of your suite. Anything less than an immediate release of ACR 7 for CS5 is a failure to address this issue--it's beyond unimaginable that users who are leveraging about $800 worth of your products are experiencing very basic workflow issues. Please let us know when this will be resolved.

The processing in Lightroom 4 is different than that in CS5 (using ACR 6.6 and earlier). There are two solutions available.

1. Install the ACR 6.7 plugin (available at, which handles the Lightroom 4 processing more accurately.

2. If you don't want to use ACR 6.7, then use Process Version 2010 in Lightroom, which matches the processing with earlier versions of ACR. You can switch the process version for each photo in the Develop module, in the Camera Calibration panel (very bottom panel on the right).
