Error msg when open workboobk

[gastoncs]

Hi all I have a problem when I assign a full file path address to this method

 
    On Error Resume Next
    Set mwkbWorkbook = Application.Workbooks.Open(Direccion)
    On Error GoTo 0

I get this error.
Title:=DocMgrAddin
“Error=Method~ofObject~Failed”

And after I press OK this next msgbox appears.
“Error Addin Toolbar”
“Error 0-“

And the workbook opens normally , but I still get the message.

One more thing I am using a dictator application, where I configure the toolbars and the menu bars, I don’t know if that is the problem; I am opening that workbook throw a dictator application.

I hope I was clear

Thanks in advance.
