PsychoPy version error

I developed an experiment on my own computer using PsychoPy version 2025.1.1, and it runs without any issues. However, it doesn’t work properly on the lab computers at the university because they don’t have the updated version installed. Even after installing the latest version, the experiment still doesn’t run and throws the following error:

“DLL load failed while importing QtCore: The specified procedure could not be found”
Also:
“Experiment ended with exit code 1 [pid: 9108]”
and
“Neither wxPython nor PyQt could be imported so GUI is not available.”

Can you please help me solve this issue?

at first glance, it sounds fairly fundemental so I’d be tempted to uninstall and reinstall psychopy and then check that one of the demo experiment eg strrop work ok.

If that’s ok, then go back to your source pc and get a fresh copy of your experiment and copy that to the lab PC to try.

As a general rule,we’re very particular to choose a particularon a release version for each academic year and to never use newer versions on personal devices - it typically stops things like this happening which can be a pain to fix. Sometimes its easier to place your laptop side by side with the lab PC and to recreate the experiment from scratch than to try to find out why it’s not working on one device.
