1. Download your chosen addon

2. Extract the files to a folder on your desktop.

3. Open your WoW folder.

Please note, if you are using the Retail version of WoW, you want to use the _retail_ folder. If you are using the Classic version, you want to use the _classic_ folder. Everything else remains the same, as outlined below.

If using a PC, the typical default install path is:

C:\Program Files\World of Warcraft

If using a Macintosh, the typical default install path is:

Macintosh Main HD (or whatever you renamed it to, if you did)/Applications/World of Warcraft

4. In the WoW folder, create a new folder called Interface (if it doesn’t already exist)

5. Open that folder, create another one inside it, called AddOns (again, if it doesn’t already exist)

6. Open the AddOns folder

7. Copy the files from the folder on your desktop into the AddOns folder

8. Your final path should look like:

PC:

C:\Program Files\World of Warcraft\_retail_ OR _classic_\Interface\AddOns\< ModAFolderName >\< files >
C:\Program Files\World of Warcraft\_retail_ OR _classic_\Interface\AddOns\< ModBFolderName >\< files >
C:\Program Files\World of Warcraft\_retail_ OR _classic_\Interface\AddOns\< ModCFolderName >\< files >

Mac:

Macintosh HD/Applications/World of Warcraft/Interface/Addons/< ModAFolderName >/< files >
Macintosh HD/Applications/World of Warcraft/Interface/Addons/< ModBFolderName >/< files >
Macintosh HD/Applications/World of Warcraft/Interface/Addons/ < ModCFolderName >/< files >

(where < ModAFolder > < .B. > < .C. > are the names of the actual folders that the mods create)

9. Log into game. At the character select screen, there should be an "AddOns" button in the lower left corner. Click on that. If any of the mods in the list that pops up say "out of date" or some such, choose the "Load Outdated AddOns" option.

10. Log the rest of the way into game, you should be up and running now. :)

The should be saved in a single level folder. One of the most common reason that UI's wont load is that there is a sub-folder inside the Custom UI Folder

1. Is there any chance that you have 2 WoW directories?

ie: C:\Program Files\World of Warcraft\Blah blah blah and C:\World of Warcraft\Blah blah blah, or anything like that?

If so, that may be the problem. Try putting your ui files in the other one.

2. Did you make sure that the files aren't in a sub-folder within your custom folder? See the graphical interpretation above.
