Hi,
I am new to PsychoPy (and Python in general) and I am experiencing some trouble after I’ve only just installed the current standalone version of PsychoPy3: PsychoPy simply won’t start.
I’ve re-installed it, still no change. Also, I’ve tried following advise found in similar threads, however, I cannot make it work for some reason. Cleaning preferences and app data also proves to be difficult as I cannot find userPrefs.cfg nor appData.cfg as suggested in the Troubleshooting section.
I ran the PsychoPy app with command prompt using the following line of code (as has been suggested for similar problems):
C:\Program Files (x86)\PsychoPy3>python.exe -m psychopy.app.psychopyApp
This yields the following message:
Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\runpy.py”, line 193, in _run_module_as_main

However, I cannot really make sense of this, so any help is really appreciated. If anyone has any suggestions on how to solve this problem, I’d be very thankful!
