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

OS: Win7 32bit
PsychoPy version: 2020.2.4-win32
**Standard Standalone?: y
What are you trying to achieve?:
i’d like to continue developing a task in psychopy, but can’t get psychopy to open.

What did you try to make it work?:
i’ve tried uninstalling, reinstalling, and deleting appdata config files. rinse and repeat.

What specifically went wrong when you tried that?:
Include pasted full error message if possible. “That didn’t work” is not enough information.

this all started while i was working on a task. i was copying and pasting components into a routine, and noticed that psychopy was starting to lag. i thought it would be wise to save and restart psychopy before anything really weird happend, so pasted one last component (of course - i got greedy), then went to save. i forget all the text involved, there wasn’t much, but the real scary part was the “segmentation fault” that psychopy reported. i hoped that it had properly saved, and closed the program. i do not believe i was ever successfully able to reopen psychopy after that happened.

any thoughts on how to proceed?

when i try to open an psychopy experiment i get the above error about missing DLL.

Based solely on the error you’re getting, I would guess your version of scipy is out of date - however I can’t think why this would break whilst using PsychoPy… I think the best approach is to update scipy and see what errors you get from there.

To update it:

  1. Find Command Prompt in your start menu, right click and choose “Open As Administrator”
  2. type cd C:\Program Files\PsychoPy3\Lib\site-packages to go to your site-packages directory
  3. type pip install --upgrade scipy

Thank you!
That seemed promising, but I got the following error:

It looks like PsychoPy is retaining some presence on your PC, have you tried to open it since last rebooting? It may be trying to access scipy in the background, which is causing the Environment Error

Thanks again. I was able to reinstall scipy, and psychopy is now running again. Thank you thank you thank you!
