I don't quite understand this code. The server is using win32com (ie,
not comtypes), but the client code seems to be using comtypes rather
than win32com (but it's hard to tell as the client code is missing the
imports etc). But at face value it appears one of the machines might
have an older version of comtypes installed.

Can someone tell me what is going wrong. The following works on one

Here is a COM server implemented in Python:
|from win32com.server.exceptionimport COMException
import pythoncom
import sys
import os
from string import Template
import logging
import logging.config
class Connector:
_reg_clsctx_= pythoncom.CLSCTX_LOCAL_SERVER
_reg_clsid_= "{0CE25AEB-1AFA-4DA7-97BD-F93CDBFB376C}"
_reg_desc_= "Python Test COM Server"
_reg_progid_= "Compy.Connect"
_public_methods_= ['Process', 'Status']
_public_attrs_= []
_readonly_attrs_= []
def Process(self, what):
pass
def Status(self):
return Template("""
Current Directory: $dir
Installed: $script
PythonPATH: $pyPath
""").substitute(dir= os.getcwd(),
script= os.path.abspath(__file__),
pyPath= sys.path)
if __name__== '__main__':
import win32com.server.register
win32com.server.register.UseCommandLine(Connector)

It registers ok. When it is run it causes the following to occur on the
production machine but NOT on the development box:
|>>> cc= CreateObject("Compy.Connect")
cc.Status()

I have installed comtypes 0.6.2. Running Python 2.6.6
