You'd need to have Python 2.7 installed.

If on Windows, you can add that during installation, it will be available for Inkscape only, as far as I know, and will not mess up your system Python version - then you don't need to do anything else.

If you install the Python system-wide, or have it installed elsewhere, then in the preferences file, you can define which Python to use. In that case follow the instructions given here: https://answers.launchpad.net/inkscape/+question/215655#comment-2

Hello, I receive the following message:

File "synfig_output.py", line 396     raise AssertionError, "Unsupported param type %s" % (param_type)                         ^ SyntaxError: invalid syntax

Whenever I try to export a file.

the problem appears to be that you are using Python 3 (which isn't yet supported) to run the python code instead of python 2.

Regards,

Same with HP plot file

Traceback (most recent call last):   File "plt_output.py", line 25, in <module>     from uniconv_output import run, get_command   File "D:\Program Files\Inkscape\share\extensions\uniconv_output.py", line 66     except Exception, inst:                     ^ SyntaxError: invalid syntax

Can you help me export to Synfig?

Thanks
