Lightroom only gives option to edit in Photoshop 2015?? In preferences, it will not allow me to change the external edit program to Photoshop 2017 which is the current CC product. What can be done to sync lightroom 2015 CC to Photoshop 2017CC?
Go to Additional External editors and choose what version you want to send the images to. Normally the top external editor will be the latest, but sometimes it depends on your order of installing or updating.
