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")
Again, this sounds like an issue with erwin, not python/pywin32.
Cheers,
Mark
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.

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