While trying to install either Windows 7 (beta – retail versions) or Windows Vista, some users have experienced the following error message:
The error message dialog screen during Windows setup looks like this:
This error code simply means that Windows cannot verify the installation files.
Solution:
Although “Windows cannot copy files” error message is frustrating, it’s actually a simple problem. All it means is that your Windows installation disc is just dirty or damaged.
1. First, make sure you clean your disc with water and a lint-free cloth (NOTE: wipe from the center of the disc to the outside edge ONLY or you can scratch the disc).
2. If that doesn’t work, you will need to either borrow a copy of Windows 7 or Vista and reinstall (using your own license key).
3. Burn a copy of the original disc (make sure you burn at a lower speed then the maximum rate).
4. If all else fails, contact Microsoft for a replacement disc if yours was smudged or damaged at time of purchase.
