win32com: error 80004005

[ago]

I am trying to make the win32com HelloWorld server work with a VBA
client but I get:

Run-time error '-2147467259(8000 4005)':
Automation error
Unspecified error

I googled for the error but the suggested solutions (commenting out
_reg_class_spec _ and putting the server on the python path) do not seem
to make any difference (to be precise, unless I comment out
_reg_class_spec _ I cannot register the server at all) . The server
works under the python client but not on excel vba. I also tried to
debug with win32traceutil. py but I can only see the trace when using
the python client, not with excel. Any hint would be appreciated.

### PYTHON SERVER ###
class HelloClass:
_reg_desc_ = "Python Test COM Server"
_reg_clsid_ = "{91281AFC-25DF-4400-8868-FDBFCA2612A2}"
_reg_progid_ = "Python.HelloHe llo"
_public_methods _ = ['Hello']

def __init__(self): pass
def Hello(self): return "Hello"

if __name__ == "__main__":
import win32com.server .register
import sys
#sys.argv.appen d("--debug")
win32com.server .register.UseCo mmandLine(Hello Class)

### PYTHON CLIENT (WORKS) ###
import win32com.client
obj = win32com.client .Dispatch('Pyth on.HelloHello')
print obj.Hello()

### VBA CLIENT (ERROR 80004005 WHEN EXECUTING "CreateObje ct") ###
Public Sub test()
Dim obj As Object
Set obj = CreateObject("P ython.HelloHell o")
MsgBox obj.Hello("ago" )
End Sub

I solved it. If someone else is in the same situation...

It was due to a defective installation. I reinstalled python and pywin,
re-registered the server and everything worked well.

The only thing I see wrong is that the Hello method
doesn't take any arguments, but the VB code is passing one.
It works fine for me if I remove the arg.
When registered with --debug, you should still be able
to see the output in Pythonwin's trace collector window
even when the object is instantiated via VB.
