Same problem here!
Since today PS CC 2018 won't open photo's and in the Creative Cloud Menu, Photoshop & Lightroom CC are blue with the text "install" but after pressing install it starts installing, but after the install it remains blue with the install text. I have de-installed both programs and re-installed them but with out any results.
When I open PS he starts with the message that he could not synchronize colour settings because file with colour settings could not be found.
Please help! Thanks!
