It has been reported that if you clean install version 1607 and then try to install 4.9.7 it will show that error. There are threads about it on here, Samsung haven't got the right signature on drivers so it doesn't run them at all. You don't need Magician anyway as SSD runs perfectly fine without it.
If you already have win 10 on PC and then get Anniversary update, the drivers will still work, it only applies to a fresh install.
