This is a bit of a doozie (and different from the other threads I found upon searching).
Basically, I’m running a 64 bit version of Windows 10.
I recently installed Standalone Psychopy 1.85.0 (32 bit) to replace an older version (downloaded in Dec 2016) because that version suddenly stopped working on my computer. It turns out that this new version doesn’t work either.
What was happening was that after clicking on the icon, the splash screen would appear, and then disappear with no application launched. This happens for both versions of Psychopy.
The Command Prompt gives the following output when ran from there:
I entered: “D:\Program Files (x86)\PsychoPy2\python.exe” “D:\Program Files (x86)\PsychoPy2\Lib\site-packages\psychopy\app\psychopyApp.py”
Traceback (most recent call last):

ImportError: DLL load failed: La procédure spécifiée est introuvable.
This problem persists when I do a clean install of Standalone Psychopy 1.85.0 on a different laptop with a totally new installation of Windows 10 having no other Python setups on it. It also persists when I install Psychopy in Anaconda.
If someone could point me to whatever packages I ought to install, I would greatly appreciate it!

EDIT TO ADD: Yes, I’ve tried clearing out my .cfg files, but that hasn’t worked either T_T
