Push it between the coils as far as it will go, and position it opposite the open side of the hook.

By pulling on the screwdriver shaft, stretch the spring so you can fit one of the coins between the two spring coils nearest the short end.

Put a screwdriver shaft through the short end of the spring so that you can hold it with two fingers on the shaft either side of the hook.

Hook the long end of the spring over something secure (I was able to hook it over one of the jaws of a bench vice).

The coins and flat bar are used to stretch the spring.

Run the G540 software and verify that the Programmer works correctly.

When Windows has rebooted, connect the programmer to a USB port, and wait for Windows to install the driver files (which may take several minutes).

When the drivers have installed, reboot to re-enable driver signature enforcement.

A Windows Security dialog will be displayed during the process - click 'Install this driver software anyway'.

When Windows has rebooted, install the USB drivers in the normal way.

When the Start-up Settings screen is displayed, press the key to disable driver signature enforcement.

When the Choose An Option screen is displayed, click Troubleshoot, then Advanced Options, then Start-up Settings, then Restart.

Under Advanced Start-up, click Restart Now.

Click Update & Security, then Recovery.

Click the Start menu and select Settings.

Make sure that all your work is closed.

To do this (make a note of or print the following instructions as you won't be able to read them after step 4): To get round this, you need to temporarily disable Windows 10 driver signature enforcement, then install the USB drivers.

The problem is that the USB drivers are not signed. If you install the software for theGenius G540 EPROM Programmer on Windows 10, the main software package (G540EngSetup.exe) should install correctly but you will probably get an error when you try to install the USB driver package (StglCproUSB_Installer.exe).
