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

51 views (last 30 days)
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

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

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.
