Device Not Found (STM32F0xx) - CMSIS DAP debugger

I am trying to debug an STM32F030R8 microcontroller using Kiel uVision (v. 5.23), running on Windows 10. Our debugger is the CMSIS DAP debugger.

After rebuilding all target files and attempting to load the connected debugger and microcontroller, I am getting "No Debug Unit Device Found" errors:

Here are my settings:

I have visited this page (https://developer.mbed.org/handbook/CMSIS-DAP-MDK) and followed it to this page (https://developer.mbed.org/handbook/Windows-serial-configuration#1-download-the-mbed-windows-serial-port) to install the drivers, ignoring the note that apparently these drivers aren't needed on Windows 10 (I don't understand why?).

My debugger + MCU were plugged in and supplied with power, and all my browser windows were closed down. I got the error message "No mbed Microcontrollers were found" when trying to install the drivers. Not sure if this is why they mention that the installation isn't required by Win10, but if that is the case, where can I get the appropriate drivers for using this debugger on Win10?

Thank you!
