Step 1:
Copy your WarCraft III version 1.22 Folder in your Program Files or which directory you have placed it. So if for example you had it this way.
C:\Program Files\Warcraft III
(This is the 1.22 version of WC3, the reason why it is recommended to be copied is because you may not be able to view your 1.22 replays if ever you want to view them. I got loads of replays so yeah.)
copy it then it should be
C:\Program Files\Copy of Warcraft III
(This will be the directory of your 1.23 patch, after doing step 3 rename this folder to whichever name you like but i prefer renaming it to "WarCraft III 1.23")
Step 2:
Download the .dll files and .mpq files for patch 1.23 here -

Step 3:
Extract the downloaded file to your newly copied folder. Copy the files inside the folder you just extracted. Paste it on the main WC3 directory(C:\Program Files\Copy of Warcraft III) A message will be asked whether to replace the existing files on your folder, Answer Yes and you're good to go!
