You mentioned Lightroom CC (5.7.1) which are two different versions of Lightroom.
Lightroom 5.7.1 is one version back than the current one.
Lightroom CC2015 is the current version and this is the version that contains face detection and dehaze feature.
Go to help menu in your Lightroom program and choose about Lightroom and make sure it is CC2015 and not 5.7.1
unfortunately I have 5.7.1 ;-(
I paid for the CC. Where do I get the correct one?
Which operating system do you have?
Is it 32bit or 64bit?
Lightroom CC runs only on 64bit machines.
Check minimum system requirements : System requirements for Photoshop Lightroom for Mac and Windows OS
Thank you.... that's the answer ;-(
I still use win 10 32Bit
It's time to change !
Yes, you need 64 bit machine to run Lightroom CC.
Hi, i have LR 6.5.1 with win10-64 bit and i miss face detection and dehaze.... How i can get it? THX
