Open the map : C:\Program Files\World of Warcraft\Interface\AddOns. And put in the folders i puted in the .zip file. Now start your WoW. Press the addon button when you are at your character screen. And select the addons you whant.

Thanks

I'll try it in the morning.

Yeah but there's just one thing...
Not all the addons work (in some classes and in some versions)
Don't just enable all and put a cross to where it says enable outdated (or something)
Instead experiment with them and gradually enable the ones you need.
I think it affects the gameplay and latency somehow if you have ALL the addons installed.
Correct me if I'm wrong
Also be carefull with the dependencies. Some addons make other addons not working. There's thousands of people who create the addons and most of them don't read the forums what others have created.
Not to mention worked WITH them.
