Installing oTree on Windows

Important note

If you publish research done with oTree, you are required to cite this paper. (Citation: Chen, D.L., Schonger, M., Wickens, C., 2016. oTree - An open-source platform for laboratory, online and field experiments. Journal of Behavioral and Experimental Finance, vol 9: 88-97)

If the below steps don’t work for you, please email chris@otree.org with details.

Step 1: Install Python

Download and install Python 3.7 (oTree is not yet compatible with Python 3.8). Check the box to add Python to PATH:

Enter this command at the prompt:

pip3 install -U otree

If you get an error like this:

error: Microsoft Visual C++ is required (Unable to find vcvarsall.bat).

To fix this, install the Visual C++ Build Tools.
