The Microsoft Windows 8 (and later) operating system has an automatic block that prohibits the installation of device drivers having absent, invalid, or self-signed digital signatures.

In order to be able to install the Robox USB Link driver on Microsoft Windows 8, you must temporarily unblock this lock with the following instructions:

•From the side pop-up bar (right side), select the Settings icon;

•Select the Edit PC Settings button;

•In the list (left side), select the General item;

•In the list (right side), look for Advanced Startup (bottom of list) and select the Restart Now button;

•Select the Troubleshooting button;

•Select the Advanced Options button;

•Select the Startup Settings button;

•Select the Restart button and wait for the system to reboot;

•Press the F7 button (which corresponds to Disable Signature Driver Imposition) and wait for the system boot to complete;

•Install the Robox USB Link driver.

When the system is next rebooted, the lockout will automatically return but will no longer affect the drivers already installed.

NOTE: for operating systems later than Microsoft Windows 8, consult the documentation for the specific operating system.
