Downloaded, unzipped. Unzipped folder gave me another folder named Umbrella, that folder gave me another folder named Umbrella, then that folder gave me an Engine File Folder, a Team_18_Working File Folder, a Manifest_NonUFSFiles_Win32 Text Document and a Team_18_Working Application 170 KB (this file has a white U emblem in a dark blue circle). When I click the application folder nothing happens.
