Driver signing error in Windows 10

Starting with Build 23f, our drivers are both signed by Lynx (with a SHA2 certificate) and counter-signed by Microsoft (for Windows 10 installation).  This should allow easy installation on any version of Windows operating system from Windows Vista through Windows 10.  On some installations of Windows 10, Secure Boot must be disabled to allow third-party drivers to be installed.  This is done in the UEFI BIOS on your computer.

To disable Secure Boot: From within Windows 10, hold the Shift key while selecting Restart. Go to Troubleshoot > Advanced Options: UEFI Firmware Settings.

Find the Secure Boot setting, and if possible, set it to Disabled. This option is usually in either the Security tab, the Boot tab, or the Authentication tab.

Save changes and exit.

When the computer restarts you should be able to install the driver.
