For now it's just taking up space so it's not really a pressing, show stopping problem. Have you tried using Windows cleanup tool to get rid of it? It usually works fine but can take a lot of time.

Also worth noting is that it's supposed to self delete ten days after the install so you may just want to wait and see if that happens.
