Could you post the full path of your Camera Raw plugin folder?
Hard Disk > Applications > Adobe Photoshop CS4 > Plug-ins > File Formats > CameraRaw.plugin
Hard Disk > Applications > Adobe Photoshop CS4 > Plug-ins > CameraRaw.plugin
Thanks. ACR plugin is in the wrong path. Please:
1. copy the plugin to: Hard Disk -> Library -> Application Support -> Adobe -> Plug-Ins -> File Formats -> CS4 -> CameraRaw.plugin
2. Delete plugins in other paths
I've never used this path before. In fact, in my office computer, it installed well with the path I posted. And, when I install CS updates, plug-ins install inside Photoshop's folder in Applications. Here, in my home, the installer won't work however. I'm not contradicting you BTW, it's possible that both paths work equally. I'll try it, thank you. One more question: when you install it and go to "Get Info", what version does it say? I updated today in my office, and it still says 5.5
