I guess you need to give some information about your automation in order for the community to provide a better answer.
In this case I think you are using an excel activity and a namespace is not declared or duplicated and you are trying to either get data from it or run a macro.
can you share your XAML file and the file you are trying to access please, I´ll be more than happy to help.
Sub Recursive(FolderPath As Variant, destfolder As Variant)
Dim Value As String, Folders() As String
Dim Folder As Variant, a As Long
Dim SApp As Object
ReDim Folders(0)
If Right(FolderPath, 2) = “\” Then Exit Sub
Value = Dir(FolderPath, &H1F)
Do Until Value = “”
If Value = “.” Or Value = “…” Then
Else
If GetAttr(FolderPath & Value) = 16 Or GetAttr(FolderPath & Value) = 48 Then
Folders(UBound(Folders)) = Value
ReDim Preserve Folders(UBound(Folders) + 1)
Else
If Right(Value, 4) = “.zip” Then
Set SApp = CreateObject(“Shell.Application”)
SApp.Namespace(destfolder).CopyHere _
SApp.Namespace(FolderPath & Value).items
End If
End If
End If
Value = Dir
Loop
For Each Folder In Folders
Call Recursive(FolderPath & Folder & "", destfolder)
Next Folder
