Hello All,
I am running into an issue with my simulink apps not showing up in the apps toolbar. The toolbart has some apps present, but the ones I need (Parameter Estimator, Simulink Test, etc) do not show up. The apps I need are within packages that I have already installed and have licenses and access to use. I am using an Enterprise licensing program through my job, if that helps at all. So far, I have ran the product installer multiple times, have tried adding them from the "Get Add-Ons" block (already installed so does not work), and have looked for help through the community but haven't had a solution yet. Thanks for any help.

Based on your description, I am under the impression you have tested good theories already what happens. If you have an enterprise license, your IT will be helpful and of course MathWorks support too. Here are a few thoughts:
  • The "ver" command returns all installed products. They might not be licensed for you (on purpose or on error), the the product files are there
  • To understand where the problem is, you could try an example and see if/what error message you get. Lets see Simulink Test https://www.mathworks.com/help/sltest/gs/create-a-simple-baseline-test.html. What do you get if you run the command?
