Unable to set value in in connection to application

[pvalle6]

For all bugs, please provide the following information:

Expected behavior and actual behavior

It should change the value (which can be confirmed in the connected program) and confirmed by
simulation.flow_sheet.Operations.Item("TIC-100").SP.Value

The actual behavior is an error. Which is literally littered all over the internet and no good solutions are posted in 99.9% of stackoverflow and the solutions that do exist are often not working.

Steps to reproduce the problem

1. Load Aspen HYSYS File using Aspen_HYSYS_Python

import win32com.client as win32
simulation_name = aspen_hysys_file
aspen = win32.DispatchEx('Hysys.Application')
simulation = self.aspen.SimulationCases.Open(os.path.abspath(simulation_name))
self.act_doc = self.aspen.activeDocument
self.flow_sheet = self.act_doc.Flowsheet
simulation.flow_sheet.Operations.Item("TIC-100").SP.setValue(-32, "C")
