Gour Saha commented on SLIDER-942:
----------------------------------

[~elserj] if you have python 2.7.x try installing 2.6.x. 

You don't need to uninstall 2.7.x or point the default python in the path to 
the 2.6.x version. You can set the property _*agent.python.exec.path*_ in the 
global section of app config to this older python path and let Slider use that 
version. The value should be set to the full path to the python binary (e.g. 
/usr/bin/python26 say).
