Can't open psychopy builder



I am having trouble opening psychopy. I started using psychopy a few weeks ago and up until now I have been able to open it. I’ve tried following the instructions on this page (, but I can’t find the files for data cleaning.

I’m not receiving any error messages, it just won’t open. I am using Windows 10 and PsychoPy version 1.84.2.

Thanks in advance!


If you can see it in the task bar try this:

If not, run psychopy from the command prompt and see if you can get an error messages there:

"C:\Program Files (x86)\PsychoPy2\python.exe" "C:\Program Files (x86)\PsychoPy2\Lib\site-packages\psychopy\app\"
