Can't uninstall TS3 Supernatural

[JBoTheAwesomest]

I'm hoping to install my Sims Supernatural expansion, but apparently I already have it installed. When I go to uninstall it (to reinstall it) it never goes away! It's a 6.56 MB file that won't go away and is preventing the installation of my game.

Have you ever installed it? Does its content show up in-game? 

When is this file happening - in installation or uninstallion? What is it?

What is your operating system?
