I've installed the Create Cloud app on the main users account on my Mac. I've also installed Premiere. However, when I log out and log into another user on the computer, the Creative Cloud app doesn't run correctly. the "window" is empty (no graphics or text in the window, just white, except for the top which says Creative Cloud). I've also noticed that the folder Adobe Creative Cloud isn't available me to me.
I believe you are referring to the blank white window of CC desktop app.
