Application does not appear in applications folder
On OS X Mountain Lion, there is an application (not from the Mac App Store) that does not appear in my applications folder, but it DOES appear in Launchpad and I would like to delete it. How can I remove it? Since it is not from the Mac App Store, I cannot click the "x" or drag it to the trash.
MacBook Air, OS X Mountain Lion (10.8.2)
