Upgrade Line 2153 : Waiting for C:\$Windows.~BT\

[CivicCenterCNB]

WHen using the script in intune I'm having some issues with some computers when I deploy the script it does not create the $Windows.~BT folder?

So the process is stuck at 0% since it can't find the folder. I'm not sure how to fix this issue?

Wait for setupact.log to appear

        **$setupactLogPath = 'C:\$WINDOWS.~BT\Sources\Panther\setupact.log'**
        $maxDuration = New-TimeSpan -Hours 2
        $startTime = Get-Date

        LogMessage -message ("Started monitoring the upgrade process at $startTime")
        LogMessage -message ("Will wait for $maxDuration")

        while (-not (Test-Path $setupactLogPath)) {
            LogMessage -message ("Waiting for $setupactLogPath to appear...") -Type 1 -Component 'Upgrade'

Basically what that is telling us is that ServiceUI.exe started the Windows11InstallationAssistant.exe but the installation assistant didn't do its job. Manually run Windows11InstallationAssistant.exe on one of the devices and see if it gives any clues as to why it's not working.
