I Had The Same Thing Happen I unpacked the iso and ran the setup.exe and got that error message. Then I burned the iso on a DVD and ran it by booting up on the DVD and had no problems.
I downloaded the new one listed in the op and it upgraded fine, using it right now. The one that says untouched.
I am not able to install Net Framework 3.5. I tried the usual fixes that worked with Windows 8 but they don't work with this new version. Any ideas?
Mount the ISO and do the following in a command prompt: Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:E:\sources\sxs /LimitAccess Replace E: with the letter of the mounted "DVD" Drive.
