Readline should have been installed in your user environment
automatically after your upgrade so I am surprised it did not work for
you. Do you have readline installed in your User environment? How are
you launching IPython? You shouldn't have to touch your
appdata/canopy-1.3.0.1715.rh5-x86_64/lib/ and you can probably remove
the older appdata/canopy-1.1.0.1371.rh5-x86_64/lib/ as well. If you
don't see readline in your environment, install it using enpkg readline.
