Register COM Matlab Application TLB for certain version on when multiple versions installed

Hi,

I have multiple versions of Matlab installed, essentially all from 2009b up until present version (because I'm developing a plugin for simulink).

Only one of my Matlab versions is registered among the COM apis I can find for instance in Visual Studio "Add reference" dialog.

How do I register the COM API for a different version? I've tried using regsvr32 on mlapp.tlb but this is not the way to go about this as I understand it?

Best regards

Start up the version of MATLAB you want, with the /register flag

[Arvind Pandey]

I m sorry but I didn't get that. Can you please suggest the steps to follow for that. Thanks for the suggestion

[Walter Roberson]

Start up a Windows command window. "cd" until you find matlab.exe (or whatever its exact name is.) Then at the Windows command line,

matlab.exe /register

[Arvind Pandey]

Thanks for the steps.

In Windows10, only <matlab.exe -regserver>, not <matlab.exe -register>, worked for me.

The command changed in time, but unfortunately I am not sure I can track it down in the documentation.

Hi, why not working command order in matlab 2018a:

matlab.exe /register

error is:

Undefined variable "matlab" or class "matlab.exe".

Current folder is: K:\Program Files\MATLAB\R2018a\bin

[Maria Avitha Francis]

What is the name of your .exe file ?

[Walter Roberson]

That command should be executed at a Windows command prompt.

Note: as of R2020b, you can use the MATLAB command

comserver('register')

[Hakan Basargan]

Please note that this solution for the Windows.

1. Run the Terminal.
2. Go to the matlab root by using cd command (until you find matlab.exe)
3. Then matlab.exe/register

Thats all.

In MATLAB 2020b this solution does not work. It wreturns in the command window:

Warning: Unrecognized command line option: register.

See https://www.mathworks.com/help/matlab/matlab_external/register-matlab-as-automation-server.html for R2020a and later.
