That's it, you're done! Proceed to creating your experiment:
Empirica is build on industry-standard open-source web technologies which run best in Unix-like operating systems such as Linux and MacOS.
Running Meteor apps on Windows can be unreliable, as apps struggle to install and launch. Whilst stopping and trying again multiple times (as well as making sure there are no processes that slow down the installation of the Meteor files) might work, it is not recommended.
In order to run Empirica reliably in Windows, you will need to enable developer settings within advanced Windows settings and download/install the new version of Windows Subsystem for Linux (WLS2).
If you are a Windows user and get stuck at any point in the development process, please contact [email protected] or join the Slack channel for community-based technical support on a wide range of topics.
