You should better ask something like this in the How to install thread. If you're ingame and have a look at the mod list and everything shows up, I guess that you have installed CPP correctly. If you are still unsure about it, have a look into the installation guide. Be aware of the current state of the guide, some things have been changed, since the installer will cover most possible installation scenarios.
