Simply put, it's not working for me. I uninstalled a few addons with the Minion and they're still there in the addons folder. If I can provide any more information, let me know. I've been able to remove addons before like this, I think. I'm not sure what went wrong this time.
Make sure that you don't have two copies of WoW installed.

Hmm.. not sure why I would. Any easy way to check? I wouldn't know where to look. I noticed that with my recent installation, it installed to Users/Public/Games instead of Program Files. Not sure why it did that. Something to do with permissions, I think.
