How to install custom matlab app

Hey I made a custom matlab app and I am trying to share it with the rest of my team. I have been testing to see if I could install it myself onto my computer however I get this into the command window when I try to install it.

I assume you developed it, so what is your definition of "install"? Did you compile it into a standalong executable and are trying to run that on your computer?

If you have any more questions, then attach your .mlapp file with the paperclip icon after you read this:

I created the app through app designer, then I clicked share -> MATLAB app. I am unable to share the .mlappinstall file here. When installing I put the .mlappinstall file into my current matlap file path and then double click, this pops up a window that asks me if I want to install. As soon as I click install the above error is shown in the command window.

Hi @Harris Naser,

I tried to reproduce the error but for me it's working fine can you provide some more details of the target machine you are trying to install.

Thank you

Hi Harris,

I understand that you are getting the above error while installing the app in MATLAB. I tried reproducing the error, but your app is working fine for me.

Alternatively, you can also try it by installing using the MATLAB Command Line Interface:

matlab.apputil.install(<mlappinstall file>)

Attaching below the documentation of the command for your reference-

Hope this resolves your query, and you are able to proceed further!
