>>404502I don't know how to fix the problem, but I can guide you to install Windows 10.
Since you are on Windows 8/8.1, you can use KMS and then switch to Digital License through the accessibility upgrade.
1) Ensure you are running 8.1. If you are on 8.0, update it, ignore all non-genuine messages.
2) Run "slmgr -ipk (Windows 8.1 Pro KMS key,google it, it is on microsoft website)" on a cmd windows with administrative prviledges
3) Use any KMS application. Does not require it to contain a service which renews the 180-day limit.
4) Upgrade to Windows 10 Pro through the Accessibility upgrade.
4.5)You can choose to clean install Windows 10 Pro after verifying it is activated with a digital license in PC Settings
5) Your problem might be solved
