Why MATLAB cannot install my app and get stuck in installation?

I packaged an App and I am trying to install it on other machines. It works fine on my machine, it gets installed easily, but when I try it on other machines, something odd happens: it seems that if I have already installed a toolbox/app on a machine, my app gets installed properly; if it is the first app installed, I get a weird response. Basically, the installation starts, but it seems that matlab is stuck in a kind of a loop, cause the icon doesnt show up in the app list and if I want to close Matlab, it says it's busy and asks me if I want to wait or close the program. Oddly, the folder with my code is correctly present in MATLAB/Add-Ons/Apps. 

I tried to install this app on 3 different machines, with MATLAB R2016b and R2017a. The app is created with MATLAB R2017a.

One possible reason for this to happen is that Add-Ons folder not writable.

To fix this

1) Go to Add-On install directory you are using:

       From MATLAB desktop, go to Preferences

      Select "Add-Ons", and check that the Add-Ons install folder is writable.

2) Try changing the Add-On install folder to a different location (try the user's home directory or desktop, for example). 

Changing Installation Folder to a writable folder should fix this.
