CopyFile Error 70 [Excel 2010, VBA Only]

I am attempting to create an install file.

There are some users using Outlook 2003 and others using Outlook 2010. The macro ensures the msoutl.olb is installed for both versions. But I can't get the CopyFile Command to work without erroring out.

All paths are correct and I have admin rights to all files/folders...

Option Explicit

Function fCopy(sFile, dFile)

    Dim xlObj As Object
    
    Set xlObj = CreateObject("Scripting.FileSystemObject")
        xlObj.CopyFile sFile, dFile, True
    Set xlObj = Nothing

End Function

Sub Control_Install()

    Dim SrceFile As String, SrceFile1 As String
    Dim DestFile As String, DestFile1 As String

    If Len(Dir("c:\program files\microsoft office\office11", vbDirectory)) = 0 Then
        MkDir "c:\program files\microsoft office\office11"
    Else
    End If

    If Len(Dir("c:\program files\microsoft office\office14", vbDirectory)) = 0 Then
        MkDir "c:\program files\microsoft office\office14"
    Else
    End If

    SrceFile = "p:\work comp\tog analysis controls\office11\msoutl.olb"
    SrceFile1 = "p:\work comp\tog analysis controls\office14\msoutl.olb"
    DestFile = "c:\program files\microsoft office\office11\msoutl.olb"
    DestFile1 = "c:\program files\microsoft office\office14\msoutl.olb"
    
    Call fCopy(SrceFile, DestFile)
    Call fCopy(SrceFile1, DestFile1)

  
End Sub

Removed the

overwrite:=True

still getting Error 70

I was getting the same error (70). I read that someone solved it using the FSO, create object, etc...
It didn't work for me.

I altered the function as follows but I am getting Error 448 Named Argument Not Found

Function fCopy(sFile As String, dFile As String, ovrWrite As Boolean) As String

    Dim xlObj As Object
    
    Set xlObj = CreateObject("Scripting.FileSystemObject")
        xlObj.CopyFile Source:=sFile, Destination:=dFile, overwrite:=True
    Set xlObj = Nothing

End Function

I did that. It turns out that I was still using the file (outlook library in an Addin). I disabled the Addin and it worked perfectly. Thank you.
