I just purchased and downloaded Adobe Photoshop 2017 CC to my Mac. My graphic designer used Adobe Photoshop CS6 in making some business documents. He has sent me the original files but I am unable to download them and am getting a message saying I do not have a program to support the document. Yet, I have on my Mac currently Adobe Photoshop 2017 CC. I would love some help!
Thank you in advance!
Presumably it's a PSD file and you're using: File > Open. Are you having any other issues with the application?
Try resetting the Photoshop preferences, which you'll find under the General tab in preferences.
