Windows Error Code 0×80070017 Solution

While trying to install either Windows 7 (beta – retail versions) or Windows Vista, some users have experienced the following error message:

Error 0x80070017 Windows cannot copy files required for installation. These files may be corrupt or missing. Make sure all files required for installtion are available, and restart the installation. Error code: 0x80070017

The error message dialog screen during Windows setup looks like this:


This error code simply means that Windows cannot verify the installation files.


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.
