HI, downloaded and installed Photoshop CC X64 on my Win7 Ultimate X64 version, graphic ATI Radeon with last driver, RAM 8Gb. At lauch PS/CC open the window then few secondes later is closing without any error message, Windows event tracing without any reported error. Called chat support without any corrective solution. Logout/login from Cloud, start with "shift" to bypass plugin load, tried with "alt+shift+ctrl" to clear preferences, same problem. I've seen on internet lots of reporting related to this bug, but no solution yet. Tried CC on my second computer: Win 7 Ultimate X64, 16Gb, Nvidia graphic with latest driver and exactly the same problem. So what is doing Adobe, I was trying to buy CC+Lightroom, but I think I will stay with my CS6 which is working perfectly. Any solution ??? Regards. Alan.
