 This appears because your Excel trust settings do not allow an add-in to manipulate another workbook's VBA code, which the ExcelPython add-in needs to be able to do to perform its tasks.
 
 To change this trust setting, select File > Options > Trust Center > Trust Center Settings > Macro Settings and ensure the checkbox labeled 'Trust access to the VBA project object model' is checked.

+This means that there was an error in running the ExcelPython server script (`xlpyserver.py`) and it can happen for many reasons.
+
+The most likely cause is that you haven't installed the [Python for Windows extensions (PyWin32)](http://sourceforge.net/projects/pywin32/) library into your Python distribution. Failing this you should consult the specified log file, which will show you the output of the Python interpreter including any errors that might have been raised during the script's execution.
