[python-win32] Win32: -2147418113, 'Catastrophic failure'

[Steven Manross]

And just to reiterate what Mark said, but also validate that this is the case from code:

You should be able to run this without issue… (and validate pywin32 works fine)

mydict = win32com.client.Dispatch("Scripting.Dictionary")

… since the “Scripting.Dictionary” COM class lives on every windows installation since Windows 2000 (or earlier).

Hello Team,

My code was working fine from one week in jupyter notebook.
Today i just did a kernel restart in jupyter notebook and my code stopped working.

Not sure what happened after restart. Tried all options but not able to resolve.
So through to get help from here.

Basically i am trying to get erwin api through => win32com.client.Dispatch("erwin9.SCAPI")

but getting error.

Giving Code as well as error below.
Please advise what corrective action should be taken.
I have tried to upgrade pywin32 module but still same error.

Code:
import win32com.client
erwin = win32com.client.Dispatch("erwin9.SCAPI")
print('Connected')

Error:


com_error                                 Traceback (most recent call last)

During handling of the above exception, another exception occurred:

     89 else:

     91     IDispatch = getattr(IDispatch, "_oleobj_", IDispatch)
