Unfortunately, only the latest version of a support package is available for installation from the File Exchange or Add-On Explorer, and there is no official way of downloading or installing previous versions of a support package. This is a general limitation that applies to all support packages.
We recommend using the latest Simulink Real-Time Target Support Package version on all development computers for the best functionality and performance. To update an existing support package installation, re-install the support package. Make sure to run a software update on the Speedgoat target computer(s) as well using the "Update Software" button in SLRT Explorer.
For future reference, you can keep a copy of the "Download Only" files from Add-On Explorer when you first install a support package in case this issue arises again.

Hi Nicolas,
As far as I know, this is not possible by default as of now. I suggest that you reach out to the MathWorks support team ( for further assistance on this topic.
