Issue running my own standalone app

I developed my own application using Matlab's App Designer, and afterwards packaged it as a "Standalone Desktop App".

I installed the Matlab Runtime installer, installed the app itself and then I could run it as a standalone.

Then, I added some functionalities and developed a version 2 (v2) of that same application. Packaged it. installed it, but then it did not work as a standalone. It works fine within Matlab, but as a standalone I can only use the toggle bars, buttons...and it doesn't execute the callback functions. I thought it might be some designing mistake, but turns out that after installing v2, v1 stopped working too!

In summary:

• v1 of my own app was working fine as a standalone
• when I installed v2, both v1&v2 stopped working

What could be the cause of this? How do I fix this?

Any help is much appreciated!

It's an old question, but the answer could help someone. I had the same problem with a standalone app that was installed in more than 50 computers and it made deal with three causes:

(1) Windows firewall has blocked service (perhaps due to an update of the Windows itself or a new network policy), so you have to unblock;

(2) An old version of Windows, so you have to update it; or

(3) Matlab Runtime crashed and you have to reinstall it.
