Microsoft is blocking users from updating to 1903 if they have Intel RTS RAID software installed, as my Predator laptop does. They demand you update the software, and when you do, directly from Intel's website, Microsoft still won't update and will throw up the same error.
I've spoken with Microsoft and Acer support for this issue, and neither has an answer besides reinstalling the OS, losing all your info, and basically starting everything over from scratch. Which I won't do for an OS update. Everything is up to date in my PC, drivers, chipsets, BIOS, and I can't update. Has anyone had this issue, and has anyone resolved it without killing everything?
