In the last tutorial, I explained how to find out your Warcraft 3 CD key. Now I show you how to change the CD key of an installed version of Warcraft 3.
PLEASE BACK UP YOUR WARCRAFT 3 REGISTRY BEFORE CONTINUING!!
You will need this Warcraft 3 Frozen Throne CD Key Changer package.
Extract the files from the archive and launch “cdkey.exe” for Warcraft 3: Reign of Chaos and “FTkey.exe” for Warcraft 3: The Frozen Throne. In the Window, click “Change CD Key” and enter your new CD key. If you don’t see this button, please scroll down…
What can I do when the “Change CD-Key” button doesn’t show up?
The Warcraft 3 CD key is not stored in the Windows Registry as many other games do, it’s encrypted and saved somewhere in your “war3.mpq” file. In order to change the key, the application needs to know where your installation of Warcraft 3 actually is. When the button isn’t there, you don’t have the right registry entries.
In order to create the registry entries, please download Lescos Warcraft Toolkit. Open “LWT.exe”, go to the “Registry” tab and browse for your “Warcraft III.exe” file. Then click “Make entries”.
Restart the CD key changer tools, the link should be there now.

Thanks for nice tutorial. I copied Wc3 folder from old desktop so obviously the registry entries were not there.”Lescos Warcraft Toolkit” helped.

Thanks! It worked!
You are brilliant! This makes it much easier to swap cd keys for myself and friends.
Thanks a lot!

@Tmill420:
No, you can’t create a new CD key. All you can do is replacing the existing one with another one. But the new key MUST be a valid one (e.g. from the cover of your WC3 CD).

Error 0×85200068:

Make sure you have the latest version of Warcraft 3 and that your path is correct, d:\\ doesn’t sound right to me, there should be only one backslash!

yeah i got the same error about the “setup was unable to add…” maybe the problem is that my frozen throne isn’t on program files i installed it on an other folder called games :/

As long as you installed the game with the official installer (then the registry entries will be there) it doesn’t matter where you installed the game to.
