title: VB6 IDE cannot load MSCOMCTL.OCX after update KB 2687323
body: <p>After windows update installed security update <a href="http://support.microsoft.com/kb/2687323" rel="noreferrer">KB2687323</a>, my VB6 project fails to load. Displayed error message is "'[project_vbp_path]/MSCOMCTL.OCX' could not be loaded--Continue Loading Project?". Note that the path in the messeage is the vbp file folder path instead of the control's registered path.</p>
  
  <p>Details:</p>
  
  <ol>
  <li>MSCOMCTL.OCX is registered in the usual system32 folder.</li>
  <li>The executable produced by exactly the same project, an hour before the update runs fine and loads the updated MSCOMCTL.OCX (I have checked it with Process Explorer).</li>
  </ol>
  
  <p>The security update description states that MSCOMCTL.OCX has a new fixed version. So I checked the project properties for "Upgrade ActiveX Controls" checkbox. I tried it both ways; checked and unchecked to no avail. VB6 IDE refused to load the upgraded OCX.</p>
