title: How to install VS6, SP5, and Proc Pack on Windows 7?
body: <p>Need to get Visual Studio 6 Processor Pack installed on Windows 7 (32 bit).</p>
  
  <p>First i installed VS6 + SP6, which prevents the PP from installing. I uninstalled VS6 and re-installed VS6 and am trying to install SP5.</p>
  
  <p>It is now complaining that MDAC 2.5 or 2.6 needs to be installed first. I've tried 2.5, 2.6, and 2.8. All run through the little extract progress dialog and appear to finish. But SP5 still fails with this:</p>

  <p>Any ideas on getting VS6 + SP5 + PP installed correctly?</p>
  
  <p>EDIT: Alternatively, any way to get VS6 (or just VC6) + SP6 + PP installed correctly? Processor Pack refuses to install on SP6, insisting on SP5.</p>
  
  <p>EDIT: I found a <a href="http://support.microsoft.com/kb/872907" rel="noreferrer"><strong>KB article suggesting a registry change</strong></a>, and that got SP6 + PP installed, but i'm getting this error, which is apparently indicates that PP isn't installed:</p>
