Using macro, but required user to run the macro

This is the basic, user still can skip this by changing date on his computer

Private Sub Workbook_Open()
    Dim Expired As Date
    Expired = "20 Jul 2013"

    If Now() > Expired Then
        MsgBox "File " & ThisWorkbook.FullName & " expired"
        ThisWorkbook.Close
    End If

End Sub

Next step, you may add a cell validation on current file to avoid skipped by user with changin the date on his computer Once the expiration msg appear, it will write in sheet1 cell A1 a word EXPIRED, then everytime file open, it will check that cell and also the date on current computer, if one of that criteria match then it will still close the workbook.

    If Now() > Expired or *Sheet1**.Range(**"A1") = "EXPIRED"* Then
        MsgBox "File " & ThisWorkbook.FullName & " expired"
*if Sheet1**.Range(**"A1") <> "EXPIRED" then
***   Sheet1**.Range(**"A1") = "EXPIRED"***
**ThisWorkbook.Save
       End If
*         ThisWorkbook.Close
    End If
