pyILPer can't load DLL

[dingebre]

So, I've had a go at uninstalling and re-installing Anaconda both for "all" users and just for me, I also did it unchecking and checking the box to allow the installer to modify the system PATH and verified that the library path where the PyQt5 dll's are located is in the PATH.

I verified that PyQt5 is in fact installed (it's in the list) but it still crashes in the pyilpermain.py file at line 136 which is:
"from PyQt5 import QtCore, QtGui, QtWidgets"

I highly doubt it is the fault of pyILPer, but something in my installation/configuration. I've searched the Anaconda boards but have not found anything that has helped. Anyone have any ideas?
