# Requirements

Four Seasons is coded in Python 3, so in order to run it you need:

* [XPPython3 Plugin](https://xppython3.readthedocs.io/en/latest/index.html).
* [Python 3.6](https://www.python.org/downloads/) or greater
* X-Plane 11.50 or greater<br>

Follow this [documentation](https://xppython3.readthedocs.io/en/latest/usage/installation_plugin.html) in order to install XPPython3 and/or Python 3.6+

{% hint style="info" %}
**I*****f you still need Python 2.7 or you are running X-Plane v10**, then download the legacy version (1.10).*

*Then you need:*

* *Python 2.7.x (*[*https://www.python.org/downloads/*](https://www.python.org/downloads/)*)*
* *Pyhton Interface Plugin by Sandy Barbour (*[*http://www.xpluginsdk.org/python\_interface.htm*](http://www.xpluginsdk.org/python_interface.htm)*)*

*Other than for the plugin, the rest of the installation procedures should be the same.*\
*Sorry, but I'm not testing the plugin on old systems.*

*Note: the legacy version is not maintained anymore*
