Thank you for your reply.
1. When I try to run the associated AdobePatchInstaller.exe, I get a message "Update Failed"; "This patch is not applicable for you. . ."
2. When I look, for example, in the downloaded folder AdobeCameraRaw8.0All-x64-050614143245 > Assets1.zip, I only see one file "1002" with no extension. Is this the binary? If so, I'm not sure what I am supposed to do with it. It is not an executable and Win7 wants to know what I want to open it with. When I search for 1002 in C:\Program Files\Adobe\Adobe Photoshop CC 2014, I see no such file, so I do not understand your replacement comment. Pardon me for perhaps being thick, but I do not understand.
3. I did not yet try your step 3.
