I have been using After Effects CS5 (10.0.2) for forever and recently upgraded to CC 2015. I have the Trapcode suite in CS5, but cannot find the plugin location in my files to transfer it over to CC 2015. I have checked in the "Plug-ins" folder in "Adobe After Effects CS5" as well as checked in the package contents for the application itself. I am still able to go in and use the plugins in CS5, so they have to be somewhere, right?
You should download new installers from Red Giant. The old plugins that worked in CS5, may not work in CC 2015. AE has undergone a dramatic change in the underlying code in CC 2015.
Most 3rd party plug-ins are using installers that reside in the media core library. You cannot and should not just copy or move these around because of the major changes being made to the structure of AE. You must use the installers.
Thank you! I was not aware
