[FIXED] How do you fix this error: "ImportError: DLL load failed: The specified module could not be found." using PyQt5

Issue

I am currently using Python 3.6.8 and PyQt5. My program was working fine but after a Windows Update, everything stopped working.

Here is the error:

Traceback (most recent call last):
  File "main.py", line 10, in <module>
    from PyQt5 import QtWidgets, QtCore, QtGui
ImportError: DLL load failed: The specified module could not be found.

Solution

It looks like the environment variables have become corrupt after the update. In the simplest case, it should just be

Adding your DLL location of python, for example,

(C:\Program Files\Python35\DLLs)

in the path in Environment variables. You can also see some others possible solutions here
