When you download something it will not automatically be executable.
You will need to make it executable manually using the chmod command
or the chmod() or fchmod() C functions. Or else when you open the
file for writing using the open() function, you can specify that the
file should have the execute bits set.

Try:

$ chmod u+x application_V2
$ ./application_V2

sudo is not magic :)

Make sure that you have told the operating system that you want to be
able to execute the file.
