Application in storage manager not visible in the applications folder

I am trying to free up storage space on my computer. There is a very large application that I tried to download but the download then failed. The application is now taking up space, but is not fully installed so I can't use it. I would like to delete this app to free up storage space. The appication shows up in my aboutThisMac>Storage>Manage>Applications window, but when I press the delete or show in finder buttons nothing happens. Moreover the app dosen't show up in finder>applicationsfolder or when I search it in spotlight. How can I delete this app from my computer?
