Failure to launch
Make sure you have the ST-LINK V2 software installed.
When you attach it you should get a new removable drive (like a USB Flash drive) added to your system.
In the device manager you should get a “Universal Serial Bus Devices” -> “STMicroelectronics STLink dongle” device.
You should also get a “Ports (COM & LPT)” -> “STMicroelectronics STLink Virtual COM Port” device.
The “ST Visual Programmer” should recognize it and be able to read from it.
