How to download Quest Helper for World of Warcraft
Hi, here's a video on how to download Quest Helper for World of Warcraft.
In order to download any addons from Curse, you will need to download the client. Go to about 0:51 in the video, and click on the orange button that says 'Download'. On the next page, you will see several options. Click the one which says 'Install w/ v4 client'. Now, follow the instructions on screen.
I'm sorry that I couldn't show you this in the video, but I have already downloaded the client.
