Installing unsigned drivers on Windows 8.1
« on: December 26, 2014, 03:06:16 AM »
Hi All

If you have recently moved to Windows 8.1 and need to install a USB driver (such as the USB-CDC driver, or your own, or an old one that you have used for some time and trust) but Windows says that it failed due to it not being digitally signed you will need to restart the PC first in a mode that allows installing them as older Windows versions did (with warning - "install the software anyway").

The following video shows how it is done: https://www.youtube.com/watch?v=UPm_6aejOlo
