What precise version of LR are you using?
The A7 II requires LR 5.7.1.
The A7R II requires LR 6.1.1 or LR CC 2015.1.1.
Thanks for your answer. My version is LR 5.7 with Camera RAW 8.7
So, but the Software tells there is no update available.
Perfekt! I found the download for 5.7.1 and it works. You are my hero! Thanks.
