Error When Trying to Run Experiment

Builder

I have completed building my task and when I go to run it a separate box appears with errors preventing my task from running. Below is a copy of the error message that appears. I have been able to run this task on my previous computer, but I got a new one and now it wont run.

Traceback (most recent call last):
File “C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\gui\qtgui.py”, line 15, in
from PyQt4 import QtGui
ModuleNotFoundError: No module named ‘PyQt4’

During handling of the above exception, another exception occurred:

Hi @hgill16, this has been fixed and will be in the next release of PsychoPy:

Hello,

Thank you for getting back to me so quickly. When will the latest version come out?

Hope

Hey! I’m having the same problem I installed the lastest version of PyschoPy 3.0.5.

Thanks @TaliaRoman, there will be a new release very soon with the fix included (see link above).
Apologies for the inconvenience :slight_smile:

@jon when can we expect the new release ?

I’m currently testing it on a clean virtual machine to make sure it’s all working. Might be able to release today!

It’s now live at the usual place:

Hi there,

I’m still having this issue:

Any thoughts?

That looks like your installation is broken. Either not all the files are there or they’ve moved, would be my guess

Ahh, ok , I’ve no idea how that has happened.

I’ve tried uninstalling and re-installing PsychoPy, but I’m still getting the same error message when I try to run anything. Any suggestions?

For anyone wondering about the above issue, it turned out to be a problem caused by the university security system. Our university service desk tweaked the CyberArk policy to allow PsychoPy to install in Program Files; users need write access to the PsychoPy program folder in order for it to run properly. Once those permissions were set, and I’d logged out and back in, the program functioned as expected. Hope this is helpful for anyone in a similar situation.
