Restoring Windows 10 'Setup failed to validate the product key' error

Restoring Windows 10 ‘Setup failed to validate the product key’ error

When you try to upgrade Windows 10 Pro from a previous version of Windows or perform a clean reinstall, version upgrade, or Windows 10 upgrade repair, you get the following error message: “Something happened, the installation failed to verify the product key.” At first, Windows setup usually works fine, but after the “We’re getting some stuff ready” screen, you get the above error.

The “Setup failed to validate the product key” error can occur if you’re updating your system using a Windows 10 ISO, an installer created using the media creation tool, or a physical Windows 10 installation DVD. At this point, you can do no more than click “Close” to exit the installer. If you repeat the installation, you’ll get the same error message. Here’s what you can try to do to get around the error.

 

What causes the “Setup failed product key verification” error?

What causes the "Setup failed product key verification" error?

Third-party AV interference: It has been confirmed that the updater may be blocked from communicating with external servers by an over-protected third-party suite. In this case, you can solve the problem by disabling real-time protection or removing the security program completely.

Unpacked installer already in the temp folder: Another possibility is that the update tool will trigger this error because it already finds the unpacked installer in the temp folder. If this scenario applies, you can solve the problem by running the Disk Cleanup Utility to remove all temporary files.

The license key is not attached to the installation media: It turns out that the problem may also be caused by a log file (setuperr.log) in situations where the user tries to update using the installation media without the license key. In this case, you can apply the license key with a series of CMD commands.

Damaged system file: A corrupted system file may also be responsible for this error message. It is very likely that some corrupt dependencies cause the updater to terminate prematurely. If this is the case, a full DISM analysis may solve the problem.

Missing configuration file: Another possible scenario is when the upgrade media you are using does not have a large configuration file needed for installation. To fix this, you can simply create a configuration file using Notepad.

If you encounter this problem, reboot your system and perform the following preliminary checks:

1.) Check that the system has the latest Windows updates installed.
2.) Run an SFC scan on the system. The system file scan detects and recovers corrupted system files.
3.) Delete temporary files. To do this, press Win + R, open the Run window and type temp. Press Enter to open the Temporary Files window and delete all files.

Repeat the process with the %temp% start commands and prefetch.

4.) If this is an edition update, we can do it with Windows Update instead of ISO. However, if you have studied the ISO file, you should have correctly identified the cause.

5.) For systems associated with the area, you should temporarily remove it from the area. A good reference to help you with this can be found on the Microsoft site.

6.)Temporarily remove any third-party antivirus software from the system to prevent it from interfering.

If all of the above attempts do not work, we can try the following solution. However, since this requires reinstalling the system, we recommend backing up your data beforehand.

  1. Extract the ISO file using free third-party decompression software.
  2. Open the Notepad file, copy and paste the following contents:

[EditID]
[Channel].
[Retail].
VL
0

3. Save this notepad file under the name ei.cfg in the Sources folder inside the installation ISO file.
4. Run the setup.exe file to run the setup wizard. You can also try creating a bootable USB drive from the file and use that USB drive to repair or reinstall.
