Well, the way I installed it (and it works flawlessly) in either TS2010 or TS12, is that, I think after running the installer and entering my serial, I looked in my Trainz folder for the CCC/Cabon City Classic folder. There was either a CDP file or a file called tlcc62m.dll - I forget which. In the case of the DLL file, I renamed the extension to CDP and then simply imported it via ContentManager. It may help to change your Windows settings to "show extensions of known file types" to checked, since, by default, this feature is disabled.
