title: Why the flag bit LOAD_TLB_AS_64BIT of LoadTypeLibEx does not take effect
body: <p>sample code</p>
  <pre><code>ITypeLib* pp;
  TLIBATTR* a;
  //C:\Program Files\Microsoft Office\Office15\MSPPT.OLB
  LoadTypeLibEx(_T(&quot;C:\\Program Files\\Microsoft Office\\Office15\\MSPPT.OLB&quot;), (REGKIND)(REGKIND_NONE| LOAD_TLB_AS_64BIT), &amp;pp);
  pp-&gt;GetLibAttr(&amp;a);
  </code></pre>
  <p>Check that the value of a-&gt;syskind is always equal to 1（means SYS_WIN32）.</p>
  <pre><code>enum tagSYSKIND
  {
      SYS_WIN16   = 0,
      SYS_WIN32   = ( SYS_WIN16 + 1 ) ,
      SYS_MAC = ( SYS_WIN32 + 1 ) ,
      SYS_WIN64   = ( SYS_MAC + 1 ) 
  }   SYSKIND;
  </code></pre>
  <p>Whether the calling method is wrong, why the flag bit LOAD_TLB_AS_64BIT does not take effect.</p>
  <p>The expected value is SYS_WIN64</p>
