kill excel instance

You are only setting the Excel Object to nothing if you close it there.
You should set it to nothing regardless. Put the duplicated code after the if statemnt. It won't hurt to set it to nothing twice.

Follow the steps above with everything.

Here is a module I use to close my apps.

Option Explicit
 
Private Sub Command1_Click()
 Dim frm As Form
  Dim obj As Object
  For Each frm In Forms
     If frm.Name <> Me.Name Then ' Unload this form LAST
       For Each obj In frm
         On Error Resume Next
           Unload obj
           Set obj = Nothing
       Next
       Unload frm
       Set frm = Nothing
     End If
    Next
    On Error Resume Next
      For Each obj In frm
        Unload obj
        Set obj = Nothing
      Next
      Set frm = Nothing
      Unload Me
End Sub

This will not work with Excel objects as it is more used for VB variable objects.

Without seeing all your Excel code we can not determine what your leaving open. You MUST close and destroy all Excel objects and quit and destroy the application(s) object(s) in order to release all references to Excel and allow it to close.
