I am trying to interface DCS Toolbox of HYSYS software with MATLAB and when HYSYS software tries to establish communication between the two, I receive the following error:

From the error messages provided, it looks like DCS toolbox HYSYS is trying to communicate with MATLAB 7.8 (R2009a) using DDE server, which is disabled by default since MATLAB 7.0 (R14) and is an obsolete functionality.
As an alternative, we strongly suggest utilizing COM in MATLAB. Unlike Dynamic Data Exchange, Component Object Model functionality is actively being maintained by MathWorks and is the preferred workflow.
