Hi everyone !
I am trying to upgrade my friend's PC from Windows 8.1 to 10 but it turns out to be much more of a pain than I expected.
I am using the Windows 10 Media Creation Tool directly on the PC to upgrade it while keeping files and apps.
But at around 70% of the installation I get the error "Failed to install Windows 10".
I will link the setupact.log file located in $WINDOWS.~BT\Sources\Panther, but these two errors seem to show what the problem could be:
CSetupManager::Execute(295): Result = 0x80004005
CSetupHost::Execute(433): Result = 0x80004005
I have uninstalled Avast and even tried installing Windows 10 while having Windows Defender turned off and I upgraded everything in Windows Update to be sure W8.1 is up to date.

Can anyone help out ? Thanks !!
