Currently running Windows Vista Home Premium 64-bit.
Trying to upgrade to Windows 7 Home Premium 64-bit.
Each time I try to install, setup fails close to the end of "Copying Windows Files" stage.
Error code comes up: "Windows cannot copy files required for installation. The files may be corrupt or missing. Make sure all files required for installation are available, and restart the installation."
As above, the error code = 0x80070017.
Any help would be greatly appreciated; I lack computer knowledge to know exactly what is going on.
Thanks in advance.
