1618 - Summa USB driver and digital signature for Windows

Modified on Mon, 8 Oct, 2018 at 9:04 AM

Introduction

This procedure describes what to do when a Summa USB driver cannot be installed correctly on Windows 7 or Windows 10.
This installation issue occurs when the Summa USB driver version 6.7 is installed on Windows 7, which is not updated to Service Pack 3. Or after a Windows 10 update, where the old Summa USB driver (version 6.4/legacy) was already installed.

Below the device manager shows a print screen of a driver, which could not be loaded. An exclamation mark appears in front of the driver. If you right click the driver and select properties you get the “digital signature” failure
message.
To solve problems on Windows 10

Download the latest version of the USB driver from our website (http://www.summa.be/download/InstallUsbDrivers.exe) and reinstall the driver.
