So u could install the new version now?
Not sure whether you have to, but I did it because I had switched to slow ring and switching to fast ring wasn't triggering the download.I tried this and still same issue, maybe I need to try again.
But u deleted those folders BT and such aswell, yes?
ren : Cannot make file that already exists.

If you turn hyper-v off for the install there's an excellent chance you won't be able to enable it again once the update is complete.
