I have downloaded the latest camera raw files. Since I have CS4 I also had to download and install Application Manager, did that. I am still unable to install the camera raw file, any suggestions on how to do this?
the latest camera raw files are designed for the the latest cs products, cs6, not cs4.
CS4 is only compatible with Camera Raw up to version 5.7.
To work on Raw files from newer cameras, you'll have to convert them to DNGs using the free DNG converter then edit the DNGs.
What the others said: New camera = new version of ACR = newer version of Adobe products using ACR. You will have to get CS6 or muddle through with DNG converter.
