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):
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.
