Hi Cjae,
There are two small connected on your tool bar. Click on that and go to apps and it will tell you which apps still need installing. First you have to Get CC.
That's not entirely mandate, the CC desktop app will not be installed or present unless you didn't selected the option to include it in CCP (creative cloud packager)
Having said this, let me explain what CCP is.
Creative Cloud packager (CCP) is a IT tool provided by Adobe to assist and help IT administrator to install the Adobe software on number of computers silently. CCP bundles the Adobe applications and there is no need to install them from CC desktop app again if included in CCP bundle.
Thanks,
