Why shows error for connecting Matlab with Aspen Plus ?

I'm trying to use the command

Aspen = actxserver('Apwn.Document.39.0'); %34.0 ---> V8.8; 35.0 ---> V9.0; and 36.0 ---> V10.0

to connect aspen plus and Matlab. It works fine when I changed it to HYSYS. But it keeps showing the following error :

Error using feval

Server Creation Failed: Server execution failed

Error in actxserver (line 89)

h=feval(['COM.' convertedProgID], 'server', machinename, interface);

Error in AspenPlus_Matlab_Link (line 5)

Aspen = actxserver('Apwn.Document.39.0'); %34.0 ---> V8.8; 35.0 ---> V9.0; and 36.0 ---> V10.0

Could any one help me on this? It is reallt important for me.

Best regards,

Wanrong

Are you using V12.1 ?

The format you are using, actxserver('Apwn.Document.39.0') does look plausible

Yes, I am using V12.1

Hi Wanrong,

As per my understanding, you tried running the above command to connect MATLAB and Aspen Plus and got an error ‘Server creation failed: Server Execution failed’.

The error could not be from MATLAB, but rather from windows produced error.

You can check the following MATLAB Answer to resolve the error:

I hope this resolves the issue you were facing.
