You made two questions:
- I was wondering if this is necessary? No, it's not.
- I think some of my colleagues that have used my code have just been using the version of the app within 'for redistribution files only' folder, and just draggin that to their desktop. As I understand it, this has worked fine for them. If this is the case, what do you achieve by installing it? You have to be careful with the location of the app's folder - it's recommended to save it in a folder that the user has write/read privileges. Installing the app (using the "for redistribution" version) could allow the app to be used by all computer users. And you will suggest the default installation folder (in the compiler process). And, finally, the OS will have access to the version of your app (and it means nothing, right?)
I am working with Matlab standalone apps for 3.5 years. I used to provide just the installer ("for redistribution"), but now I provide just the folder "'for redistribution files-only". And since then my life is so much better! :)
