Important Lightroom 1.4 and Camera Raw 4.4 Update

The following was posted recently on the Adobe blog page site:

The Lightroom 1.4 update for Mac and Windows has been temporarily removed from the Adobe.com web site. Those Lightroom users who have installed Lightroom 1.4 should uninstall the update and install Lightroom 1.3.1.(Mac, Win) until a further update can be provided. For those not in immediate need of the updated camera support available in Camera Raw 4.4 or the DNG 4.4 Converter, it's recommended that you also continue working with the 4.3.1 versions. (Mac, Win) This decision is based on the following errors that have been discovered with the recent update:

EXIF Time Stamp Error: There is an error in the EXIF time stamp update technology that causes Lightroom to believe that the files are out of sync with the correct time stamp as displayed in Lightroom. Any ensuing metadata update will attempt to incorrectly modify the EXIF time stamp in the original raw file itself. This is the only metadata field that Lightroom will write to an original proprietary raw file. This error will not impact the integrity of your image data. The Camera Raw plug-in also will incorrectly change the EXIF time stamp in files converted by the plug-in. The information written to the XMP sidecar files or XMP metadata in the converted files will remain correct.

DNG Conversion Error(Windows Only): With the latest version of the Lightroom 1.4 and Camera Raw 4.4 applications, Adobe has included technology to verify that the image data in a DNG file is unchanged from when it was originally converted to DNG. Unfortunately, when converting to DNG using Lightroom 1.4 on Windows, the application will write an incorrect verification tag to describe the image data. When Lightroom attempts to work with those files in the Develop module, the application reads that incorrect tag, believes that there is something wrong with the raw data and will present an error. Rest assured, there is nothing wrong with the integrity of your image data or metadata. For those that have already converted their files to DNG using Lightroom 1.4(Windows only) we recommend using the DNG 4.3.1 converter to convert the DNG files you've created with Lightroom 1.4.

Olympus Conversion Error: There is an error in converting Olympus JPEG files to other formats in Lightroom 1.4 and the Camera Raw 4.4 plug-in.

To uninstall Lightroom 1.4 please see the instructions per your platform: Mac: Delete the Lightroom application in the Application folder(Mac) and Delete the following file: Library/Receipts/Adobe Photoshop Lightroom.pkg Windows: Choose the Uninstall Lightroom 1.4 menu item from the Windows start menu. The Add/Remove Program utility on Windows will also achieve the same result.
