title: win32com Excel.Application can't open documents anymore
body: <p>This was working last week but for some reason it stopped working today, maybe because of the new year?</p>
  
  <pre><code>def remove_strikethroughs(xlsx):
      excel = win32com.client.Dispatch('Excel.Application')
  
      xl = pd.ExcelFile(xlsx)
      sheet_names = xl.sheet_names
      for sheet in sheet_names:
          if any(tab in sheet for tab in tabs_used):
              #print (sheet)
  
              wb = excel.Workbooks.Open(xlsx)
              ws = wb.WorkSheets(sheet)
              for cell in ws.Range('A5:B150'):
                  if cell.Font.Strikethrough == True:
                      cell.value = '[MDU]' + str(cell)
              wb.Save()
              wb.Close()
      excel.Visible = True
      excel.DisplayAlerts = True
      excel.Application.Quit()
  </code></pre>
  
  <p>I get the following error message:</p>
  
  <pre><code>"AttributeError: '&lt;win32com.gen_py.Microsoft Excel 15.0 Object Library.Workbooks instance at 0x20920640&gt;' object has no attribute 'open'"
  </code></pre>
  
  <p>Can someone please help?</p>
  
  <p>Thanks!</p>
