I've only ever installed versions of AE off of the stand alone AE discs. I know that depending on your OS and the version of AE you're installing the location of the effects will vary. For example, under Windows XP for AE 7 I believe there is a button on the main splash page for the AE 7 Installer that allows you to install the 3rd party effects. For AE 6.5 on the Mac there was a folder on the AE disc that was named something like "3rd Party Tools" that had the installer for CC. I would be surprised if there weren't some information either in your user manual or online about where to find these effects for your particular version/OS.
If it comes right down to it you can try inserting the AE disc and searching it for 'Cycore' or 'CC'.
