2. Extract the files to your Warcraft folder -> version folder.
(Ex: Your Warcraft folder is

QUOTE(Pathname)
C:\Program Files\Warcraft III\1.21]
if you downloaded the 1.21 DLLs).
3. Backup the CURRENT DLL files in your Warcraft folder to another folder.
4. Then, copy your new DLL files (files extracted) to Warcraft's main folder.
5. Your Warcraft has now been upgraded to whichever version you've chose.
