Hi I have just used Creative Cloud to install Lightroom CC. When I attempted to launch the application Lightroom immediately crashes when it shows the splash screen. I did a google search and it was recommended that i should log out of my Adobe account and log back in. I tried this but Despite redeated attempts to log out when I click on the log out button a new screen comes up to confirm logging out I click yes to confirm and nothing happens. I have tried repairing permissions, restarting the computer, etc. Any ideas on how to fix this?
I solved my problem by installing the Mac OS X 10.10.3 supplemental update and restarting the computer. I was then able to log out of my Adobe account and log back in. I can now run Lightroom CC. Hope that this might help other users.
