Why my MATLAB Standalone Application can work on my computer but cannot run on others

I have created an standalone .exe using matlab. I know that if others want to use my .exe then they need to install the correct version for MCR. For example, my matlab version is R2016a and the MCR version is 9.0.1. However, when my friend correctly installed the MCR and try to run my program, it just didn't get him the correct answer. Moreover, when we limit the size of our input(i.e. from 100 records to 1 record), the error message even changed which doesn't make any sense. I am just thinking that my application is not functioning correctly on his computer. Could someone can tell me beside install MCR, is there any other things I need to do to make sure my program could run? Thanks.

I don't link any external libraries for my exe application, and we are using the same computer. Is there any potential computer settings that I should update?

See the FAQ: http://matlab.wikia.com/wiki/FAQ#My_standalone_executable_won.27t_run_on_the_target_computer._What_can_I_try.3F
If none of that solves it, tell us what you see in the system console window when your compiled program runs.

Thanks for your answer. My issue is actually I could run that exe on my computer, but my friend's computer cannot have the exe calculate the correct answer out.. Meanwhile, some of my other friend can run my application just with the installation of MCR on their computer. It is weird..

Do you mean that it launches and runs just fine, with no errors whatsoever, but the numerical "answer" it reports is a different number than you expect?

Hi all !
I may use your help on a similar (I guess) issue. I've built a Matlab application and used the Matlab Compiler to make a standalone application. Basically is just a GUI to change parameters and IC of a ode system (solve with ode23s).
When I download and install in on my computer, I manage to launch the app, use the different buttons or toggles, everything looks fine, but as soon as I press "run" (which i suppose to run the ode solver, that is to say the ode23s function) the function seems to run for ever, while it is suppose to take less than 1 sec.
Do you have any idea where it could come from ? Or is it normal that the program takes a (really) longer time to compute the solution?
Best wishes,
Léolo

Hi again (that was fast).
So here is what I get, almost instantaneously, when I "click on run", which is exactly what I get when using the app on my computer.
However, the solver seems to keep running (see following screenshot. It should display the elapsed time and not "Running" anymore ...
Any thoughts on this one ?
Best regards,
Léolo

I would suggest putting in a try/catch block just in case it is somehow crashing. That will not catch any kind of endless loop though.
