Pupil labs plugin installation OK, but Psychopy Crashes

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win11):
PsychoPy version (e.g. 2003.2.3):
Standard Standalone? (y)
What are you trying to achieve?:
Run Psychopy after installing the PupilaLabs plugin

What did you try to make it work?:
downloaded this

and pasted into

What specifically went wrong when you tried that?:
Without trying that solution, Psychopy crashes (does not load). I am unsure if this solution is a rpoper soution or there is a bug somewhere

At the moment we are recommending to continue to use 2022.2.5 for eye tracking studies.


Is there any update on when this might be fixed? Also, does this only relate to installation where the user is on a computer using roaming profiles? Just wondering as we have the same problem on our computers with PsychoPy 2023.2.3 which are enrolled on a Windows domain server.

Cheers, Jon

For anyone wishing to recover from borking their psychopy installation by installing the Pupil-Labs plugin, you just need to


Windows key + R, copy and paste the above into that. Hit OK.

Open the psychopy3 folder and then double click on userPrefs, which should open in notepad - look for the line with “Pupil” in it - startUpPlugins = then remove the reference to pupil-labs-blah-blah… save the file

Et voila…
