Connect Matlab with MultiSim

[jualsevi]

Hi,

I'm trying to connect Matlab 2018a (64bits) with Multisim 14.0 using Automatizacion API (http://zone.ni.com/reference/en-XX/help/375482A-01/multisim/automationapi/#wp40650).

When I try launch this code to start:

% Open interface to multisim
msim = actxserver('MultisimInterface.MultisimApp');

Matlab show this error:

Error using feval
Server Creation Failed: Clase no registrada

Error in actxserver (line 86)
h=feval(['COM.' convertedProgID], 'server', machinename, interface);

I don't know where is the problem. I had seen example codes that works well.

Thanks in advance.
