Hii
Well, not all cc go into the mods folder check if it says package file at the end of every folder if its sims3pack then double click it and it'll automatically run by the launcher, if your launcher dont work try dragging tge sims3pack to the downloads folder and if that doesnt work go to TUMBLER sims 3 cc and they wont need any launcher just WinRar and dragging the package folder to the package folder and it'll for sure work ..
Hope this helped.
