 cause the trouble. Replacing this system-wide Python installation with
 version 2.7.4, instead of 2.7.2, solved the problem.

 Could someone check what exact version ArcGIS installs. I suspect < 2.7.4.

 Unfortunately, the Python launcher discussed in the thread Helmut points
 to in comment:7 seems to only take into account minor version numbers, but
 not revision numbers, so there does not seem to be a way to distinguish
 between two versions of 2.7 on the machine.

 Is it possible to uninstall the python installed by ESRI ?

 One option would probably be to delete the registry key entries of the
 ESRI Python version, install a more recent Python (e.g. 2.7.5) and install
 the Python launcher.
