Error while installing Vista on a 8.1 PC

This problem is maybe common when installing on a modern hardware, like mine, but, I’ve trying to dual boot Vista and 10, but, after I run on my USB flash, the mouse, just does not works, I knew it was common, so, I see on google/bing a download for USB 2.0 and 3.0 drivers, and, I just find it out, in a exe file, and that can’t be for a setup part

My Specs + Mouse/Keyboard:

Intel Celeron J3060
Seagate SATA 500GB
4GB RAM
Intel HD Graphics 400

Mouse Inova (6D Optical Mouse 5V 100mA):


Keyboard: Fortrek Gaming keyboard Green: image

He wants to install Vista in a 8.1 machine, not the opposite

But, someone actually do that on a 8.1 laptop with Windows XP (and XP is older than Vista)

dude…
