So I have made an application(gui) in matlab and compiled it to an exe. My gui has a save and load button that operate as such. on save callback: save('saveGame.mat','handles');

on load callback: load('SaveGame.mat');

This works when the code is being run from matlab. However, when I run the application from the compiled exe, I get an error sound when clicking save. Does anyone know why this may be?

If you tell it to create a log when you package your app you will see what the error is, or if you run your exe from command line.

Since you appear not to be giving a path for your save file it will save it in whatever the current directory is. I forget, off-hand, what this is for an executable, but it isn't generally somewhere to be saving user files. It's possible you don't have write permission there too.
