title: AIX : cannot execute binary file, 0403-006 execute permission denied
body: <p>I am working on AIX 7. I like to know more in detail about the following error scenarios</p>
  
  <ul>
  <li>cannot execute binary file</li>
  <li>0403-006 execute permission denied</li>
  </ul>
  
  <hr>
  
  <p>for the <strong>first</strong> case, on search it was likely that,</p>
  
  <blockquote>
    <p>when you are trying to run 64 bit software on a 32 bit OS, you may
    have that error. AIX is 64 bit, and I have been trying to use mysql by
    installing XAMPP, where I am getting the above error. I assume 32/64
    bit software will be okay with 64 bit OS.</p>
  </blockquote>
  
  <p>for the <strong>second</strong> case,</p>
  
  <blockquote>
    <p>though I have logged in as a root, and file permissions are 755 [
    -rwxr_xr_x ] execution permission is denied..</p>
  </blockquote>
  
  <p>I will be very happy, if I could know why the above situations occur and the best way to resolve it.</p>
  
  <p>Thanks in advance !!</p>
