I deleted PH CC because it was crashing after I updated it yesterday and some of the functions were missing. I thought I could reinstall if from the creative cloud but it says I already have it so I can not reinstall it.
This is 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 resolve it, Run the Cleaner tool to remove Ps CC :http://www.adobe.com/support/contact/cscleanertool.html . and then try installing Ps again.
