Hey, I’m afraid that’s not going to work for you. Check out the linked thread for further details, I believe windows 10 is part of the minimum system requirements, sorry dude.
I do see this though, so if the other requirements seem to be met, see if this applies to you:
I’m not sure how driver signature enforcement works, but I’d bet that your antivirus won’t be happy about it.
In fact, I’m guessing that unless this is an offline computer only, that to pursue it would be ill advised. If it never connects to the internet and you won’t be putting unknown sourced software on it then I don’t really see it as a huge risk.
