It worked. I used 7zip to extra the iso file


If all of the above-mentioned attempts don’t work, we could try the following fix. However, doing so involves a clean install of the system so it is advisable to backup your data well in advance.
1] Extract the ISO file using Ashampoo ZIP free decompression software.
2] Open a Notepad file and copy-paste the following content in it:

[EditionID]
[Channel]
Retail
[VL]
0

3] Save this Notepad file by the name ei.cfg to the Sources folder inside the setup ISO file.
4] Run the setup.exe file to start the installation wizard. You could also try making a bootable USB out of the file and run that USB for a repair or re-install.
