I’m not sure about Linux, but for windows should work smoothly.
Hmm, perhaps different Python versions? I based on Python 2.7.11 and this template has been parsed without problems, but before downgrading Python try clues described in script.
Also you can use script via cmd, so if something would go wrong you will see output.
Btw. does it happen for every template you’re trying to convert?
Edit: yeah, seems like version incompatibilities.
