How can I solve the error of Aspen Hysys case opening "Invoke Error, Dispatch Exception: Access is denied."

Dear,

I am using MATLAB 2016a and Aspen HYSYS V9. I am trying to connect between two program and encounter the error as following:

>> hysys=actxserver('Hysys.Application')

 hysys =
   COM.Hysys_Application

>> simcase=hysys.SimulationCases.Open([cd,'\an.hsc']);

Error using Interface.HYSYS_9_Type_Library.SimulationCases/Open

Invoke Error, Dispatch Exception: Access is denied.

I tried to run MATLAB as Administrator but the result was still the same. I put the an.hsc file in MATLAB path.

Please kindly help me solve this error. Thank you very much for your help.

I have the same problem, the .m file and .hsc files are in the same folder. I tried a lot but not solved. please return the answer to me if the problem solved

Put both files, Hysys simulation case (.hsc) & the following matlab script (.m) in the same folder. Matlab Code, please modify simulation name ("Distill_Example.hsc") accondingly:

Hysys=actxserver('Hysys.Application.V10.0'); %COM Technology

[stat,mess]=fileattrib; %getting actual folder name

simcase = Hysys.SimulationCases.Open([mess.Name '\Distill_Example.hsc']); %Opening HYSYS Simulation (Distill_Example.hsc)

simcase.invoke('Activate'); %Opening HYSYS Simulation (Distill_Example.hsc)

Typically, "Error using interface" can be generated due to lack of Hysys License, therefore the program cannot initialize.

If the error persists, you can send me the simulation and I will try to make the Matlab-Sim Hysys connection.

Hi,

The .m file and the .hsc file have to be in the same folder. Then you can proceed as follow:

Hysys = actxserver('Hysys.Application.V11.0');

FileNamePath = 'File_name';

Simulation = Hysys.SimulationCases.Open([cd,strcat('\',FileNamePath,'.hsc')]);

Simulation.Visible = true;

Components = Simulation.Flowsheet.Operations;

Streams = Simulation.Flowsheet.MaterialStreams;

Fluxes = Simulation.Flowsheet.EnergyStreams;

Best regards,

Francesco

Same Folder is solution

No, it is not
