    CS4 won't open CR2


      I cannot get Photoshop CS4 Extended to open raw CR2 files from my Canon 5D MkIII. Adobe Bridge will not open a thumbnail, either. The same files open fine in Lightroom 5.6. I am working with Windows 7 Pro and Intel Core i7 on a Dell Vostro.

          CS4 use an old version of ACR if your canon is a newer model you will have to download the  ACR 8.6 and DNG Converter then create DNG  files for your CR2 files and process the DNG with the CS 4 version of ACR.


          Your other option is to subscribe to the cloud and use a newer Photoshop. $10 a month....

            Thank you. I found ACR 8.6 DNG converter and downloaded it, but was hoping there was a more elegant solution. I guess I'm upgrading soon...
