Genius G540 EPROM Programmer - Installing on Windows 10

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

  1. Make sure that all your work is closed.
  2. Click the Start menu and select Settings.
  3. Click Update & Security, then Recovery.
  4. Under Advanced Start-up, click Restart Now.
  5. When the Choose An Option screen is displayed, click Troubleshoot, then Advanced Options, then Start-up Settings, then Restart.
  6. When the Start-up Settings screen is displayed, press the <F7> key to disable driver signature enforcement.
  7. When Windows has rebooted, install the USB drivers in the normal way. A Windows Security dialog will be displayed during the process - click "Install this driver software anyway".
  8. When the drivers have installed, reboot to re-enable driver signature enforcement.
  9. 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).
  10. Run the G540 software and verify that the Programmer works correctly.

You may find that Windows periodically disables the driver, so you might occasionally have to uninstall it and repeat the procedure above to re-install it again.

Note: the Programmer draws around 230mA from the USB port when programming and can exhibit strange or inconsistent behaviour if connected to a USB port that cannot provide enough power.
