I just updated my LR and PS today, now when I keep trying to send pictures from lightroom cc to photoshop and it keeps asking me if I want to edit the original or with adjustments. When i select one it says preparing file in the top left corner of LR and then makes a duplicate and resaves it back to LR as a tiff or PSD whichever i have it set to in preferences. Any ideas? It was sending the pictures over no problem before the update.
Please keep the Photoshop application open in the background, while opening the images from Lightroom to Photoshop and check if that helps.
Do you have updated CC to the latest version? This was a bug in a previous version. As far as I see on my machine (windows 10, PS 2017 and LR 2015.10) all is working.
That message comes always from a TIFF, PSD or jpeg file.......
What type of file are you sending???
