[python-win32] Dispatching something that requires elevation

[Simon McConnell]

Hi,

I am trying to dispatch a COM interface of a program that is set to "Run as
Administrator" in the Compatibility Settings of its properties.  Running
the script w/o elevation results in a 'requires elevation' error.  Running
the script with elevation results in a 'server execution failed' error,
which I understand to be "I can't find that thing".  Removing the "Run as
Administrator" from the Compatibility settings and running the script w/o
elevation works, but unfortunately, this program needs to be run as
administrator.  When opening the program manually I have to accept the UAC
popup and cannot turn it off thanks to Group Policy.  Any clues?

import win32com.client
o = win32com.client.Dispatch("CimplicityME.Application")


gives the error:


Traceback (most recent call last):
  File
"C:\Users\smcconnell\PycharmProjects\proficy\venv\lib\site-packages\win32com\client\dynamic.py",
line 89, in _GetGoodDispatch
    IDispatch = pythoncom.connect(IDispatch)
pywintypes.com_error: (-2147221021, 'Operation unavailable', None, None)

During handling of the above exception, another exception occurred:

    dispatch, userName =
dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx)
  File

line 114, in _GetGoodDispatchAndUserName
    return (_GetGoodDispatch(IDispatch, clsctx), userName)
  File

pythoncom.IID_IDispatch)
pywintypes.com_error: (-2147024156, 'The requested operation requires
elevation.', None, None)



If I run the script as administrator I get the following error:


Traceback (most recent call last):
