Why do I get an error regarding missing "Simulink Real-Time Add-Ons" when I try to build my Simulink Real-Time model in R2024a and later?

I upgraded to MATLAB R2024a. When I try to build my existing model that I created with a previous release for Speedgoat hardware, I encounter the following error:

Error using slrealtime.internal.build.BuildHooksImpl.setup
    To build model, configure Simulink Real-Time model for target computer platform.
    Open Target Platform Selector and select a target computer platform.

Upon clicking the Target Platform Selector hyperlink, I get the following error:

Error using slrealtime.internal.HardwareConfig.openTargetPlatformSelectorFromLink
    Unable to open Target Platform Selector: No Simulink Real-Time Add-Ons are installed.
    Use Add-On Manager to install a Simulink Real-Time Add-On.

In R2023b and earlier, it was not necessary to install any add-on such as the Speedgoat I/O Blockset just to build a real-time application MLDATX file.

Since R2024a, building real-time application MLDATX files for Speedgoat hardware is no longer possible without a Speedgoat I/O Blockset installation. This is because the new speedgoat.tlc system target file was introduced, and it ships as part of the Speedgoat I/O Blockset. This also means that your existing real-time models must be configured to use 'speedgoat.tlc' instead of the previous slrealtime.tlc system target file.

Follow the steps below to build (and optionally run) a Simulink Real-Time model on a Speedgoat target computer in R2024a and later:

 

1. Install the Speedgoat I/O Blockset which is available for download from the Speedgoat Customer Portal.

In R2025b and prior, you might also be prompted to install the Simulink Real-Time Target Support Package during the Speedgoat I/O Blockset installation if you haven't installed it yet from the MATLAB Add-On Explorer.

2. Update the software on your Speedgoat target computer using:

tg = slrealtime;
tg.update;

.

3. Configure your model for R2024a or later using one of the options from the following MATLAB Answer: How do I configure my Simulink Real-Time model for Speedgoat hardware in R2024a and later?
