Having trouble loading data in my GUI

I currently created a GUI that does statistical analysis of different data sets that can be loaded by the user as excel files. everything was working fine until I packaged it and installed the app on my computer. It will no longer load the data files. I did find that my GUI will not load files that are not in the folder that my GUI is located in either.

The code I am currenlt using is:

Name=uigetfile; handles.V1=xlsread(Name); handles.V1=xlsread(Name); set(handles.listbox1, 'String', handles.V1); guidata(hObject,handles)

and the error I get is:

XLSREAD unable to open file 'Temp.xlsx'. File '\\stmartin.edu\dfs\Users\Jeremiah.Enright\MyDocuments\MATLAB\MATLABProject\Matlabproject\Temp.xlsx' not found.

This file is located on my desktop and not in this folder.

Is there any way to make it load from another folder?
