How to register wc3 files in a new computer?

[N.Knight]

Hi
I have bought a new computer and want to play wc3 on it. Problem is my original CDs have too much scratches on them due to years of use and refuse to install the game properly. So I thought why not copy the warcraft folder from my old computer and paste it into the new one. I did so but the game does not run

Is there a quick way to register the game without actually installing it?
Like some 3rd party software or something, so that I can start playing custom maps and also be able to save them, like in a installed game?

I am not worried about the original game itself or the world editor, I just want to play some custom maps and be able to save them.

Also, I wasn't able to figure out where I should put this question; if it is in the wrong forum then please move it to where it belongs.

Do you still have the cdkey?
Just register them at Battle.net and download the games from there.

Thanks
I also found this nifty tool http://www.hiveworkshop.com/forums/tools-560/warcraft-iii-registry-fixer-1-0-a-62929/ in the tools area. It did the trick.

Download it from BattleNet. Register your Warcraft III Reign of Chaos CD Key with your BattleNet 2.0 account and then go and download the full game.

If you do not have a CD Key then we cannot help you as most people will not support piracy.
