Keil MDK 5.34 st link v2 "Not a genuine St Device! Abort connection"

I'm about to start using C++ for embedded and chose STM32F103C8T6 AKA Blue Pill for my first project. Using Keil MDK 5.34 on my Windows machine I went to practice this series but I get the following error when I tap on Flash -> Download (F8). 

I tried many remedies notably, un-install/re-install the St Link V2 (screenshot below) driver, changing USB cable and port on the PC, and so on but no change in result thus far. 

 

Why do I get that error and what are you ideas on solving this issue, please?

Thanks beforehand for your time and help.
