Programmer De1-SoC Driver error

[RiccardoRoma]

Hi,

Until the other day everything was working regularly. Then, probably after a windows update, the usb driver for the De1-Soc card no longer works. I tried to reinstall, but windows gives the error: Altera USB Blaster II. Error adding driver to repository. Can someone help me?

I solved by myself. There was the problem of unsigned drivers. I uninstalled the latest security updates and it works now. Thank you
