Something that could go wrong while installing Windows 7. The backup, partitioning and other pre-requisites complete just fine. But when the installation begins to extract files and data from the DVD, you get a big error which says:
Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070017
More often than not, the simple reason behind this error is just that the DVD burning caused some little problem somewhere and corrupted a file.
There’s no quick solution, just re-burn the Windows 7 RC on a new DVD with as low a speed as you can stand. 2x or 4x should be OK. Some people are also saying that the DVD- format works more times than DVD+, but I think just lowering the burn speed should do the trick.
