"Run-time error '429': ActiveX component can't create object" error when I try to use Spreadsheet Link with Excel?

Hello,

When I run 'start Matlab' in excel link add ons, I encounter this error as well:

Run-time error '429': ActiveX component can't create object

I didn't install a Matlab, but I install matlab runtime. I execute this at CMD:

matlab -regserver

This error I get:

'matlab' is not recognized as an internal or external command, operable program or batch file.

What should I do?

[Walter Roberson]

MATLAB Runtime (MCR) is like Visual Studio Runtime library: a support package that cannot do anything itself.

You need to install MATLAB itself.

[Robert]

then, what is the advantage of MCR?

[Walter Roberson]

MCR is a library that is called by applications compiled by MATLAB Compiler or MATLAB Compiler SDK. It implements a lot of the MATLAB Execution Engine.

At the moment I do not know if it would be possible to use MATLAB Compiler SDK to build an executable that could be invoked by Excel Link.
