What happens when you try to import?
If there is an error message, please quote it word-for-word verbatim.
Why doesn't Lightroom work with these native files?
Oh, but it does - I've put hundreds of files from my 7D Mk II through Lr CC/6.
As DJ suggests, you need to tell us exactly what happens when you try.
I could import and see the preview but files would not open in the develop tab... I just got a blue window with a white x across the screen. weird because it would open files from my T1i but not the 7d MKii, figured it was still something with the newer camera...
After the OP I uninstalled. just finished reinstall and it works now...
Guess I should have done that prior to posting. Thanks for the quick response I will let you know if it has anymore hiccups...
You haven't mention what computer hardware you are using. This is always helpful. In meantime, I suggest switching off the GPU support in Performance tab of Lightroom preferences.
ok thanks... well it acted up again as soon as I undocked my laptop (even when plugged into the wall charger). Once the laptop was docked, it worked again.
turned off the GPU support and it now appears to be working while undocked.
Thanks everyone for the assistance.
