    It happens because:

    Get-ChildItem $targetConfig -Recurse

    Return both DirectoryInfo and FileInfo. And Set-ItemProperty fails on setting “ReadOnly” for DirectoryInfo.

    To handle this use:

    Get-ChildItem $targetConfig -Recurse |
    Where-Object {$_.GetType().ToString() -eq "System.IO.FileInfo"} |
    Set-ItemProperty -Name IsReadOnly -Value $false
