Try searching for the executable file by clicking the windows icon on the bottom left corner of your screen. Go to "All Programs" then search for a possible EA folder if not it could be under the "Games" folder (I don't have Crysis).
If you can't find it that way, just try doing a seach by click the Windows logo icon again and then click the search box. Type a search query: "Crysis'.
If all else fails, it could possibly be Crysis wasn't installed correctly and the icon is a dead shortcut. In that case you might want to try re-installing it.
