The Camera Raw 5.7 Update will not install. I've tried it both through Help/Updates and Software Update. Any ideas?
You can also install it manually.
Be sure to have the latest download, then open the DMG file (should do so automatic) and grab the plug in file to drag it in the correct place.
This is the path:
Library (That is on root level, not your user account library!) / Application Support/ Adobe? Plug-ins / CS4 / File Formats.
In this folder should only be one version present and it is called "Camera Raw.plugin" Under info it should say version 5.7.
