if you have cs3, the cycore effects (denoted by ‘cc’) should have been installed by default, unless the ‘install third party content’ option was unchecked. i believe this is true for all version of cs3 (trial, education and, of course, pro), but i may be wrong on that. also, i believe you can install just the third party content from the original install disk.
if you have ae7 pro (or earlier pro version) i think the third party installers were in an ‘extras’ folder or maybe ‘third party’ folder on the original install disk. within that folder is a folder called cycore, and within that, the cycorefx installer.
if you have a standard, education or tiral version of ae that is version 7 or earlier you will not have those third party effects. you can purchase a similar fx package from cycorefx.com called cycorefx hd. i believe it has all the same effects, plus several new ones, and all of them are capable of 16bpc calculations.
