ads_env call of SetExecutablePath failed! Reason: Configuration is invalid!

[Nikhil]

I am also having same error.

That error is coming straight from the Keysight-ADS integration layer, and it simply means you haven’t loaded a valid ADS configuration before trying to set the ADS executable. Here’s the shortest fix:

1. Load an ADS configuration (the one that points at your installed ADS version) before setting the

ads_env('LoadConfiguration','default');   % or the name of your ADS profile

1. Then tell MATLAB where the ADS EXE lives:

ads_env('SetExecutablePath',...
    'C:\Program Files\Keysight\ADS2023\bin\ADS.exe');

If you skip step 1, SetExecutablePath has no “configuration” to hang on to, so it gives you “Configuration is invalid!”

—If you’re not sure what configurations are available, just run

ads_env('ListConfigurations')

and pick one of the names it returns.
