Found this on another forum It may apply in part if you are doing the free download or trying to install from an ISO.
"These errors can be caused by ,
Incompatibility of hardware or software on the system
ISO that was created is corrupt, Damaged installation source files, need to recreate it
insufficient space on your C drive (system drive), limited space issue for upgrade.
Remove security and system utility software, Anti-Virus"
So this could be caused if you have an antivirus installed and running
