This thread helped me. I had numerous failed attempts yesterday and today in Windows 10 on my new Amplifi 75. Went to my wife's Windows 8 Professional. It failed twice, but then I tried the Factory reset (which I had done with other laptop), and it took. We're getting to the point where most things work all the time, so when we're fussing with hardware like the good old days, we just don't have the patience for it.
