I named your file Q_28615458.txt
Sub Q_28615458()
    Const ForReading = 1, ForWriting = 2, ForAppending = 3
    Dim oFS, oTS
    Dim strFileData
    Dim oRE
    
    Set oFS = CreateObject("Scripting.FileSystemObject")
    Set oTS = oFS.OpenTextFile("c:\users\aikimark\downloads\Q_28615458.txt", ForReading, False)
    strFileData = oTS.readall()
    oTS.Close

    Set oRE = CreateObject("vbscript.regexp")
    oRE.Global = True
    oRE.Pattern = "(""B"".*)(\r\n)"

    If oRE.test(strFileData) Then
        strFileData = oRE.Replace(strFileData, "$1" & vbTab & "#This line is special$2")
    End If

    Set oTS = oFS.OpenTextFile("c:\users\aikimark\downloads\Q_28615458.txt", ForWriting, False)
    oTS.write strFileData
    oTS.Close
End Sub

    oTS.Close

    Set oRE = CreateObject("vbscript.regexp")
    oRE.Global = True
    oRE.Pattern = "(""B"".*)(\r\n)"

    If oRE.test(strFileData) Then
        strFileData = oRE.Replace(strFileData, "$1" & vbTab & "#This line is special$2")

You probably don't have permission to write to files in the root directory.
