I recently used a trial of MacKeeper to try and get all of the extra unused files of of my MacBook Pro. Unfortunately, it seems to have either corrupted or deleted CC Application Manager. I downloaded and tried to re-install it several times, but each time, it fails. I could really use some help!
I'm currently looking to upgrade from CS6 to CC.
Please delete Adobe Folders from these locations and try instaling CC Apps using CC Desktop apps.
Also please use CC Cleaner tool. http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html
Once done then download CC Desktop app from https://creative.adobe.com
Please let us know if it helps
