Hi Mark, Thanks for the response.Here is what I am using to instantiate the server through python >>> from comtypes.client import CreateObject >>> cc= CreateObject("Compy.Connect") >>> cc.Status() The com server also fails when being accessed from vbscript. I have verified that both machines have comtypes 0.6.2 loaded. Win32com works on the same machine that comtypes works >>> import win32com.client >>> wcc = win32com.client.Dispatch("Compy.Connect") >>> wcc.Status() When I run this on the machine that fails with comtypes I get: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<COMObject Compy.Connect>", line 2, in Status pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'Python COM Server Internal Error', u"Unexpected Python Error: AttributeError: 'module' object has no attribute 'VARIANT'\n", None, 0, -2147467259), None)
You should be able to register the COM object with "--debug" on the command-line - the message printed on registration should say "(with debugging)".
Then, run win32traceutil and you should see the complete traceback from the server. Note that win32com.client.VARIANT was added quite recently to pywin32, so if the failing machine has an older version it will fail.
HTH, Mark
Do you have any suggestions as to what I can test?

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. Mark On 5/08/2012 11:13 PM, Paul Hemans wrote: Can someone tell me what is going wrong.
