I am actually using the interface ExcalibBem to calibrate an idf file simulation with a measured data and does not work at all. The objective is to match the Interior electrical equipment consumption of the model with the measured data, selecting several electrical equipment parameters. The error I get is as follows:

Error in executing the simulation program
Exit value of the simulation program: 1
Working directory : 'C:\Users\SambuKS\Desktop\EP_Calibration_MinOA\GenOpt\tmp-genopt-run-1'.
Current command String    : 'cmd /C ""C

The model is uploaded here

Edit:

Here is my .cfg file:

this is the cfg file configuration:

SimulationStart

{

// The command line below calls RunEPlus.bat.

Command = "cmd /C \"\"C:\\Users\\SambuKS\\Desktop\\My Model\\GenOpt\\Calib.bat\" \"%Simulation.Files.Input.File1%\" \"%Simulation.CallParameter.Suffix%\" \"C:\\EnergyPlusV8-4-0\\\"  \"%Simulation.CallParameter.Prefix%\"\"";

    WriteInputFileExtension = false;
}
