I installed Photoshop CC, but was unable to open it. Thinking it was a bad download, I uninstalled, but was then unable to reinstall as the CC Desktop App thinks that Phtoshop CC is already installed. HELP!
It seems your issue is resolved now, For reference this was because you deleted the Ps app not uninstalled it. So when you try to download, it shows you that Ps CC is already installed.
To resove it, Run the Cleaner tool to remove Ps CC :http://www.adobe.com/support/contact/cscleanertool.html . and then try installing Ps again.
