Troubles compiling uigetfile function and importdata ||Matlab

I finished a long Matlab code, that works just perfect in Matlab. Now I'm trying to compile the app, to use it as an .exe file on other computers.

relevant code:

[FileName,PathName] = uigetfile('*.CSV','Select the data file');
delimiterIn = ',';
headerlinesIn = 11;
A = importdata(FileName,delimiterIn,headerlinesIn); % A becomes a 1x1 struct containing data, textdata and colheaders

the code imports a .CSV file.

The uigetfile works just fine, as I used [FileName,PathName]. But at line 4 A = importdata(FileName,delimiterIn,headerlinesIn); the code stops working an I get the following Error message:

Unable to open File.

Error in => name_of_my_program.m line 4

Any ideas how to solve this problem? I can't change much in the code, as the varibales A.data and A.headliners are used a lot in the code.

Did I use the importdata function wrong? Does the importdata function not work with compiled apps?

csvreadistead of importdata does work, but as mentioned above, I'm looking for a solution, were I don't need to change all the variables in my long code. So the output got to be a 1x1 struct containing A.data, A.textdata and A.colheaders

I use MATLAB R2017a and the Appliaction Compiler within

The compiled applicarion is probably not running in the same folder as your input file, so you should update your code to generate the full path filename using fullfile:

[FileName,PathName] = uigetfile('*.CSV','Select the data file');
delimiterIn = ',';
headerlinesIn = 11;
if FileName == 0; return; end
Filename = fullfile ( PathName, FileName );
A = importdata(Filename,delimiterIn,headerlinesIn); % A becomes a 1x1 struct containing data, textdata and colheaders
