Within the past few releases, ipython changed the startup command for qtconsole from `ipython-qtconsole` (with a hyphen) to `ipython qtconsole` (with a space). The QtConsole shortcut provided by the EPD 7.x installer uses the former syntax, which is no longer supported by ipython. The `enpkg` utility only updates packages, not shortcuts.
Therefore you will need to open QtConsole from a terminal.
Enthought Canopy includes a GUI which provides a customized QtConsole among other features. It can be started either from a terminal, or with a shortcut link.
