title: Dev c++ 4.9.9.2 is installed on my windows 8.1. Warning: "Source file not compiled"
body: <p>This is my hello world program. It compiles, but when I Run it says : </p>
  
  <blockquote>
    <p>"Source file not compiled"</p>
  </blockquote>
  
  <p>I have included header files <code>stdio.h</code> and <code>conio.h</code>. 
  Any solution.? I installed code::blocks as well, I got a similar error in that IDE as well.</p>
  
  <pre><code>int main()
  {
     printf("Hello world");
     return 0;
  }
  </code></pre>
  
  <p>As it compiles, it is generating an exe file, which is not showing up in command prompt, it is somehow getting deleted(may be McAfee is doing it)</p>
