I am trying to debug a remote installation of an exe that I created using the Matlab compiler. The exe works fine on my machine and the remote system does not have Matlab, so it is difficult to figure out why the exe is not working. I will note that the exe creates a folder under the Windows Documents folder, which it then populates with data files. Is there any chance that Windows requires permissions that the exe lacks in order to modify the Documents folder? Any other general debugging tips on a remote exe installation?

It turned out I had incorrectly formatted a directory creation statement.

在 MATLAB Online 中打开

It is unlikely that is the problem, but not impossible.

You should be writing your code with the general form

filename = fullfile(....);
[fid, msg] = fopen(filename, 'w');
if fid < 0
   error('Failed to open filename "%s" because: "%s"\n', filename, msg);
end
...
fclose(fid);

If you have a permission problem then that will show up in the msg

Useful suggestion, thanks. I found this suggestion to see the error messages that the exe generates so I know where to start debugging.

Where EXACTLY is the "Windows Documents" folder? If it's under C:\Windows or C:\Program Files, then you cannot save things there. If it's under C:\Users\KAE\Documents, then you should be able to save files there.
