Error after trying to run a Matlab App "No matching files found"

Hi,

I am trying to find where is the issue while trying to run a Matlab App.

After I build the new app in the Matlab Compiler and try to run the app afterwards I get the error message:

"No matching files found".

I get this error message on the machine that has Matlab installed and also on the one which doesn't have Matlab on it.

I am working with Matlab 2015b and MCR version 9.0.

Can anyone explain in simpler words where I have to search for the problem. Is it somewhere in the lines of the main Matlab file or I make a mistake while I am building the app using the Compiler?

I have read some threads on root , appRoot (https://uk.mathworks.com/matlabcentral/answers/258854-why-does-copyfile-not-work-in-matlab-deployed-gui), absolute and relative path (https://blogs.mathworks.com/loren/2008/08/11/path-management-in-deployed-applications/) but unfortunately I can not understand what's the next step I have to do to solve my issue.

If anyone could give a hint where to start in solving my problem, it'd be really appreciated?

Thank you!

EB - where in your app code are you looking to load files? I'm guessing that your code is trying to load a file (or files) and cannot find any. Perhaps you aren't supplying the full path to the files that you are trying to load. Please provide some details.

There is an excel file with data which is necessary for the analysis within the app. However, that excel file is already included in the app (it's added to the Section of MATLAB Compiler: Files required for your application to run).

[Adam Danz]

Just to be clear, the excel file is in the exact same folder as the compiled app (not a sub-folder) and the folder is on your matlab path -- is that correct? My first hunch is the same as Geoff Hayes'.

[EB]

Yes. The excel file is located in the same folder as the app. And in the backend code of the app that file is being called at some point.
