When installing the Windows 7 beta, I received the following error:
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. Error code: 0x80070241
If you get this error, the problem is your ISO file.Â I had burned a DVD and mounted the ISO directly.Â My buddy Nate burned me a new cd from his ISO, and the installation was fine.
I think the problem occurred when I paused the download, and resumed at a later time.Â I guess Akamiâ€™s download manager isnâ€™t as robust as BITS or Bitorrent.
So if you get this error, download another ISO, or find someone whose worked.
