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. I had burned a DVD and mounted the ISO directly. 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. I guess Akami’s download manager isn’t as robust as BITS or Bitorrent.
So if you get this error, download another ISO, or find someone whose worked.
Gah!!! Are you serious!?? It took me a week to download that… 🙁 (extremely slow internet with a 200mb cap)
I dont think that this diagnosis is correct. I have a fresly installed XP Media Center machine with all the updates. When I try to install Windows 7 I get the error listed above. Bummer. But when I load a factory DVD of Vista, I get the same error. I even copied the factory DVD to the local drive and I get the same error. I will admit that the drive may be suspect…but I have had no other problems with it. Still looking for an answer.
