After you've installed the support package, you will have to do a setup. Go to the support package entry in the Add-Ons explorer, click manage, and then click the setup link for this package. You'll have to download and extract support files from ST, and tell MATLAB where they're located.

Thanks! I downloaded support files previously, and It worked. After that, I deleted these files. Some time later, I try again and I get "Failed to generate all binary outputs."

Your answer is the solution.
