If you have the R50, it requires ACR 15.2. If you have the new R50V, it requires the latest ACR version 17.3. In either event, Elements 2023 only updates to ACR 14.4.
You can use a workaround to update Elements 2023 to ACR 17.3. You must follow the instructions precisely. Here are the instructions for Windows:
- Close all Adobe applications
- Download and install the latest ACR version from this link
- Go to the following folder: C:\Program Files\Common Files\Adobe\Plug-Ins\CC\File Formats
- Copy the file named Camera Raw.8bi
- Go to the following folder: C:\Program Files\Common Files\Adobe\Plug-Ins\Elements21\File Formats (If the folder doesn't exist, create it.)
- Paste the Camera Raw.8bi file into the folder.
For Macs you must copy the file from:
Mac HD/Library/Application Support/Adobe/Plug-ins/CC/File Formats
To:
Mac HD/Library/Application Support/Adobe/Plug-ins/Elements 21/File Formats
