I have resolved the issue by uninstalling PyQt5 5.4.1 and python 3.4.0. Then reinstalling them both following the tutorial on utube from Brazo Robótico.
Not sure what I did then, but got it work after a short while.
What I did notice was that I was actually opening gui.py with the previous installation, because asgard.py didn’t open the control software.
After reinstalling python, asgard.py opens the software perfectly.
Once again Thank you for all your help.
