Is there a way to disallow or inform the user that they cant run an installable App in an older version of ML?
I have made an App that is used across my company; and have coworkers who are trying to use the app in older versions of ML where it crashes with cryptic messages. I made the app in 19a; after installing in anything older than 18a it crashes when run. Apparently, I am using some features that were added in 18a and are not back compatible (this is fine; I am glad ML is adding new features!).
The app crashes before getting to the StartupFcn, so I cant do a version test in there.
I have no problem requiring my coworkers to use 18a or newer to use the app but I need a way to communicate that; ideally it should not install in older versions or give a meaningful error when run. I am distributing the app via an internal repository.

if verLessThan('matlab','9.4') % 2018a = 9.4
disp('Version of Matlab is too old. Please open in MATLAB 2018a or later.')
% run your app

Hi Chris,
Version requirements are already enforced in that a user of an older version gets an error. It could just probably be a nicer error message provided like you're saying. I'm not in development so can't comment on their plans but I can say that you contacting them via tech support and complaining is the best way to motivate them to do things :)
