Hi Akshay,
Just want to make sure you are following the right procedure of downloading the generated code onto the board. Can you follow the steps in this video and try ?
Cheers, Abhishek

Hello I have the same problem on Windows 8.1, MATLAB R2015b. However, I don't have a problem connecting Arduino to MATLAB, but this problem occurs even if I run the example code.

In the case posted above:
The file C:\Users\Saaranga\Documents\MATLAB\untitled_grt_rtw\untitled.obj already exists and its permissions do not permit it to be written to. Delete the file and try again.
