I recently created this macro that works fine on my station (running Excel 2016) but crashes on other people's station (Excel 2010). How can I fix this to work for them?
        Sub MACRO1()

        Sheets("SHEET4").Activate
        Range("A1").AutoFilter
        Range("A2", Range("A2").End(xlDown).End(xlToRight)).ClearContents
        If ActiveWorkbook.Sheets("SHEET1").Range("A2").Value = "" Then Exit Sub

    End Sub
Again the Macro works fine on my station running excel 2016 but not on those running excel 2010. Would like to fix the code to have it run on both.
