Disallow running an App in an older version of ML?

2 views (last 30 days)
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

I will give a wrapper a try, thanks.
I see you are MathWorks staff, can we expect that version requirements will get added into the App designer or the packageing process at some point?

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 :)
