Hi... Did you purchase the CC Essentials Complete Bundle?
If so then the CC Essentials Resouce is a bonus that comes with the complete bundle. It is made up of two parts. The first part (Install.RLD) installs into Character Creator and gives you a number of sample characters found under Project > Clothed. The second part is a zip file. This just needs to be unzipped and doesn't need to be installed. It contains all the resources such as decals, scars, masks etc.
Note: Both parts of the CC Essentials Learning Resource can be downloaded from your Member Account > Order History.
