On a deadline and have 650 RAW files from a new 5D4 that I can't open. Adobe tells me I have successfully installed camera RAW 9.7, but still no luck. I was not able to do it from within Elements 14 because I can't figure out how to bring up the ribbon?/taskbar? that includes the Elements tab or the updater. Consequently I have no idea whether the update went into the program or which version I'm running. Why is something that ought to be so simple so damn complicated? I need help pronto if someone can tell me what's going on.
You can try to manually install ACR by downloading and running the standalone installer from the following page.
Another solution is to use the 9.7 DNG converter to convert your .CR2 files to DNG so you can open them in ACR. You can download it from this page.
If you're using Photoshop Elements 14, that cannot be updated beyond Camera Raw 9.5. So you cannot open 5D Mark IV CR2 files with PSE14.
You'll have to use the DNG converter instead.
