Error, can't run

[C++Raven]

I got this code sent to me, and am working with a friend to see what the problem is. We can't seem to run it at all the even try to find the problems with its errors.

It just says the system cannot find the file specified. I was told to change something towards the beginning of the code to make it run at least, but still can't figure it out.

This is the code

/*
Mississippi has 11 characters
First occurance of word "is" is at position: 1
The first four characters are:          Miss
The next two characters are:            is
Charters start at position 9 are:       pi
*/

#include  <iostream>
  #include <conio.h>

    using  namespace  std;

    int  main (  )
    {
    string  stateName = "Mississippi" ;

    cout  << stateName << " has " << length( ) << " characters\n";  

    cout  << "First occurance of word \"is\" is at position: " << find("is") <<  endl;

    cout << "The first four characters are:\t\t" << substr( 0, 4 ) <<  endl;

    cout << "The next two characters are:\t\t" << substr( 4, 2 ) <<  endl;

    cout << "Charters start at position 9 are:\t" << substr( 9, 5 ) <<  endl;

    _getch();
	return 0 ;
}
