Debugging ACR 3.1 Installation Problems

From the Adobe Camera Raw User to User forums

Thomas Knoll has suggested some troubleshooting tips on the installation of the Camera Raw 3.1 update.
(see original thread)

If Photoshop CS2/Bridge is not working correctly after you attempt to install ACR (Adobe Camera Raw) 3.1, here a some hints on how to debug common installation problems.

 

1. Make sure that “Camera Raw” appears exactly once in Photoshop’s “About Plug-in” menu. If it appears zero times, you did not install the plug-in in a correct location. If it appears more than one time, you have multiple copies of the plug-in installed.

2. If “Camera Raw” appears exactly once in the “About Plug-in” menu, then pick that item and make sure the Camera Raw about box shows version 3.1. If not, you have the wrong version of Camera Raw installed.

3. Run Bridge and pick “Camera Raw Preferences…” from the Bridge(Mac) or Edit(Win) menu. If the command is grayed out, then you don’t have Camera Raw installed in the correct place. If the Camera Raw preferences dialog does not have “Version 3.1″ in the title bar, you have the wrong version of Camera Raw installed.

If after you verify that that 1, 2 and 3 are correct, and you are still having problems, then next step is to purge the Bridge cache for any folders you have having problems with.

Also, it’s important to note that with Camera Raw 3.x, Adobe Bridge and Photoshop CS2, the proper location to install the update has changed.

Installation

This new version of the Camera Raw plug-in replaces the original Camera Raw plug-in that was installed with Photoshop CS2 and Photoshop Elements 3.0.

Updates

• The highlight recovery algorithm now limits the amount of color estimated for near neutrals in overexposed image areas.

• Support for the “UserComment” EXIF tag has been added. • The Export Settings command now only applies to the selected files.

New DNG Handling features (Photoshop CS2 software users only)

There are now two new preferences in the Camera Raw preferences dialog that control the handing of DNG files:

• “Ignore sidecar ‘.xmp’ files”:
When using the Photoshop CS2 software with DNG files, the Camera Raw plug-in conversion settings and other metadata is now stored directly inside the DNG files. Sidecar “.xmp” files are no longer required. To be compatible with settings and metadata applied to legacy DNG files created by Photoshop CS or Photoshop Elements 3.0, however, the Camera Raw plug-in by default looks for and applies settings and metadata stored in sidecar “.xmp” files.

This backward compatibility may be confusing if your workflow includes both DNG and non-DNG versions of a raw file in the same folder with the same base file name. It may become unclear which file the “.xmp” sidecar belongs to and the settings from the non-DNG file can mistakenly be applied to the DNG file.

Checking this option in the preference dialog disables this backward sidecar “.xmp” compatibility, and these sidecar files will be ignored when processing DNG files.

• “Update embedded JPEG previews”:
In the Camera Raw 3.0 plug-in, updating the Camera Raw conversion settings stored inside DNG files does not update any embedded JPEG previews. Updating the preview significantly increases the processing time and is not required for the Photoshop CS2 and the Adobe Bridge workflows. Some other third party applications, however, make extensive use of the embedded previews.

To have the Camera Raw plug-in update the embedded previews whenever it updates the raw conversion settings, select this preference.

Another workflow option is leave this preference unchecked when fine tuning the raw conversion settings, then update all the embedded previews in the DNG files before handing the files off to the third party application. To enable this workflow, the Camera Raw 3.1 plug-in added this same option to update the embedded JPEG previews to the Export Settings command whenever one or more DNG files are selected.
