Use a function as below...

Sub Macro()

If IsWorkbookOpen("Book1") = False Then
'Place your code below

End If

End Sub

Function IsWorkbookOpen(strWorkbook) As Boolean
Dim wb As Workbook
On Error Resume Next
Set wb = Workbooks(strWorkbook)
If Not wb Is Nothing Then IsWorkbookOpen = True
End Function
