I am using a Mac Pro (mid-2012 model) running OS X Yosemite 10.10.2. My Creative Cloud Desktop app will not launch. The icon is gone from the taskbar at the top of the screen. After trying to uninstall/reinstall Adobe CC, I uninstalled every Adobe app on my mac, restarted the machine, and reinstalled Adobe Creative Cloud Desktop again. When I attempt to launch the program, the icon very briefly flashes on the taskbar, but it is greyed out, then disappears.
