How do you change install directory for supportpackageinstaller

I am trying to have the C2000 target support package available in a local directory. Supportpackageinstaller automatically assigns the install directory and does not give an option to change it.

There is a MATLAB preference for the add-on install folder. See this screenshot (R2017a).

Thanks for the answer. However, I am planning to install at a location different from where Matlab wants to install.

... change the preference?

However, the support package installer tries to keep track of which packages are installed, and I suspect that if you just changed the preference then it will get confused about the packages that had been previously installed.

You can download the package from https://www.mathworks.com/matlabcentral/fileexchange/43096-embedded-coder-support-package-for-texas-instruments-c2000-processors

This will give you a .mkpkginstall file. If I recall correctly it is a zip file that can be unzipped and then you can pull out the pieces to install them separately.

However, the code generation packages such as the C2000 typically require several steps of downloading third party tools, which you would have to do by hand, and you would have to know all of the right settings in Simulink to get it to recognize the package.

Sometimes it is easier to uninstall all your existing support packages, then change the preference to point to a different location, and then install those packages back along with the new package.

Thank Walter! The downloaded package doesn't appear to be a zip file. You said one could change through preference where the package can be installed. It already shows local directory in the preferences for Add_ons. However, it is trying to install on a network drive where our Matlab is installed.

Hmmm, that appears to be an XML file, and looking at it I cannot see how it works :( It looks like it just provides a key for the add-on manager to contact Mathworks to do the downloading.
