Virtual com port driver not properly installed

Hi @KPate.6​ ,

A similar question is already asked here.

In the description of the STSW-STM32102 you can find:

Virtual COM Port driver installation package for Windows® operating systems: 98SE, 2000, XP, Vista®, 7, and 8.x.

Windows 10 does not require the installation of the Virtual COM Port driver anymore, as it is already built in.

So, if you use a Windows® operating systems: 98SE, 2000, XP, Vista®, 7, and 8.x try to uninstall the driver and reinstall the last version.
