How to Install AddOns for "World of Warcraft"by Shea LavertyUpdated September 22, 2017
"World of Warcraft" supports the use of add-ons, user-created tools to enhance your gameplay. Whether you're installing a boss mod to warn you of dangerous boss mechanics or an RP-enhancing tool to flesh out your character's history and personality in-game, add-ons are all installed to the same folder. You can install add-ons manually, or use an add-on client to install them for you.
Download the add-on you wish to install to your desktop. Unzip the folder by right-clicking it and selecting "Extract All." Copy the extracted folder and paste it into the Add-Ons folder for WoW's program files. The file path should look like the following:
C:\Program Files\World of Warcraft\Interface\AddOns\
Once pasted, the add-ons only need to be activated in-game to be ready for use.
Add-on clients simplify the installation and updating of add-ons by automating the process. Typically, you download and install the client, then select add-ons from their website and install using their "Install via client" option. Some clients instead require you to install the add-on manually, then update via the client. Curse Client, WowMatrix and Wootbit Client are some commonly used add-on clients. Some groups, like Tukui, use a proprietary client to update add-ons they produce, like the Tukui and ElvUI user interface add-ons.
To activate your add-ons, click the "AddOns" button on the character selection screen. You can select which add-ons are active for which character by selecting the character name from the drop-down list and checking the check-boxes for add-ons you want to use. Check the "Load Out-of-Date AddOns" check-box to enable add-ons listed as "out-of-date," which are often still useful. When you log in, your add-ons will be active.
