You were on the right track. Don’t rely too much on the text, just follow the pictures. I managed to install it properly, but I have the Core M3 model and, as you’d expect, it sent my device into a bootloop.
Anyway, at step 4, there are no more files to open. After you load the file that the picture shows, just press the button at the bottom of the software window (it’s shown in a picture in the instructions). After that you just copy the remaining files onto your USB drive and it can be used as a bootable drive.
Installing the drivers manually after a clean windows install is extremely difficult and quite unreliable for several of the components, but it IS possible. If you can’t go the OS flash route, you can try that alternatively.
I’ve been facing similar issues for two weeks with my device as well. Just follow my solution in the future: NEVER buy another Voyo device again 😛
