I installed the latest version of Psychopy (v2021.2.1) on Windows 10.
So, I need to run an old experiment built in an older version of Psychopy. However, when I open the “Experiment settings” and I try to select the old version from “Use Psychopy version”, the only version allowed is “latest”.
There is no other option (e.g. 3.0.5 etc)
Any suggestion for this problem?
