Windows 7 – Installation – Error – “Windows cannot install required files. Make sure all files required for installation are available, and restart the installation”


Trying to install MS Windows 7 on a friend’s computer.  Currently, she has MS Windows XP.  But, somehow that OS is no longer coming up.  Yes, it comes up when I access the computer via Safe-mode, but “No Go” when I try booting into a regular Windows XP mode.

I tried re-installing MS Windows XP a few times, but getting stuck with the installer asking for “Nvidia Network Disk”


Here is mock up of the “MS Windows 7” setup screen:

And, here is the perplexing error we are getting:

Error Header

Windows cannot install required files.

Error Message

Make sure all files required for installation are available, and restart the installation.  Error code 0x80070001.



Googled for help and the top hits suggests that for our search tag – “Windows 7” “Setup” “0x80070001” – we should try a different media.

Interestingly enough the more persuasive voices suggested USB over DVD; that is, they think the source of the problems is often bad DVD media or faulty DVD Drives altogether.

Download New Windows 7 ISO

On a working computer, Google for where I can find install binaries for MS Windows 7.   Nicest and reliable listing seems to be:

Burn ISO

On a working computer, found good tutorial on the well received and regarded MS Windows 7 Burn to DVD/USB @

The basic signpost is that we should download “Windows 7 USB-DVD Tool” from

Once downloaded, install and launch it.

Running is also straightforward:

  • Step 1 – Choose ISO File
  • Step 2 – Choose Media Type

Step 1 – Choose ISO File


Step 2 – Choose Media Type


I went against the loudest advice by choosing DVD over USB.

Try Windows 7 ISO

Once we have a new and nice Windows 7 ISO, took it to our faulty computer and tried it out.  And, thanks goodness as it works.


I know my friend is shipping her son off to college this weekend.  But, I really do hope she held back a bit of money to upgrade us from “No product key” / Trial version of MS Windows 7 to a licensed copy.

We need to pay and get a Product Key.  And, then activate it.
