SUMO with TraCI, getting OSError: [WinError 193] %1 is not a valid Win32 application

Question

Trying to run the SUMO simulation using TraCI protocol:

import os, sys
if 'SUMO_HOME' in os.environ:
    tools = os.path.join(os.environ['SUMO_HOME'], 'tools')
    sys.path.append(tools)
else:
    sys.exit("please declare environment variable 'SUMO_HOME'")

sumoBinary = "C:/Users/User/Desktop/Thesis_task/Trial_task/trial.sumocfg"
sumoCmd = [sumoBinary, "-c", "trial.sumocfg", '--log', 'logfile.txt'] 

import traci
traci.start(sumoCmd)
step = 0
while step < 1000:
    traci.simulationStep()
    if traci.inductionloop.getLastStepVehicleNumber("0") > 0:
        traci.trafficlight.setRedYellowGreenState("0", "GrGr") 
    step += 1

traci.close()

I am trying to connect the TraCI, but it is throwing this error:

OSError: [WinError 193] %1 is not a valid Win32 application

I have installed all the dependencies correctly, and also have the supporting Python version running on my machine. I followed a few older StackOverflow solutions, but none of them worked in my case.

Per the TraCI documentation:

Interfacing TraCI from Python

First you compose the command line to start either sumo or sumo-gui (leaving out the option which was needed before 0.28.0):

sumoBinary = "/path/to/sumo-gui"
sumoCmd = [sumoBinary, "-c", "yourConfiguration.sumocfg"]

However, your sumoBinary variable does not point to either of those two programs, instead it points to your trial.sumocfg file:

sumoBinary = "C:/Users/User/Desktop/Thesis_task/Trial_task/trial.sumocfg"

Which is clearly not an executable program, hence the error.
