First, go to the singer site and search for your model, and see if there are upgrades. Many of the older Futura's don't have the upgrade to work with newer Windows versions....what model do you have? If it's a 100, 200, up to 350, ( I think)..you simply can't run them on Windows 8 or up.
If you find that is the case..you can let it go..or look for an older computer with an older version of Windows on it.
