[Zope] Using win32com in Zope

Thanks very much to Alexis Roda for this one.

Problem solved. For anyone else who gets the same problem, it seemed to be 
with the installation (or lack of it) of win32com for Zope.

The solution I used was based on:

Although I didn't follow those instructions exactly, it did give me the 
registry keys to change, then re-install win32com, making it install for the 
Zope python, rather than the stand-alone Python.

Thanks again to Alexis

I have been trying to write to Excel from Zope, using win32com.

If I try the following in python, it works fine:

>>>from win32com.client import Dispatch
<COMObject Add>
>>>o.Cells(1,1).Value = "Hello"
>>>o.Cells(1,2).Value = "World"

However, attempting to do this with an external method from within Zope 
(having done my best to get all of the files it depends on copied over into 
Zope sub-directories in bin/lib):

def launchExcel(self):
   from win32com.client import Dispatch
   o.Cells(1,1).Value = "Hello"
   o.Cells(1,2).Value = "World"

I get the following error when attempting to test the external method:

Error Type ImportError
Error Value cannot import name Dispatch
Error Trace Traceback (innermost last):
File C:\PROGRA~1\ZopeSite\lib\python\ZPublisher\Publish.py, line 98, in

(Object: launchExcel)
(Info: ((), {}, None))
File C:\PROGRA~1\ZopeSite\Extensions\excelstuff.py, line 11, in launchExcel
(Object: Excel)
ImportError: cannot import name Dispatch

Dispatch is defined in win32com/client/__init__.py:

def Dispatch(dispatch, userName = None, resultCLSID = None, typeinfo = None, 
UnicodeToString=NeedUnicodeConversions, clsctx = pythoncom.CLSCTX_SERVER):
  """Creates a Dispatch based COM object.
  dispatch, userName = 
  return __WrapDispatch(dispatch, userName, resultCLSID, typeinfo, 
UnicodeToString, clsctx)

Can anyone point me in the right direction here?
