title: Error code 2753 during install
body: <p>Today I needed to re-install Microsoft Pex on my develop machine.</p>
  
  <p>I'm using Windows 7, 32 bit, Visual Studio 2010, .NET 2/3.5</p>
  
  <p>I launched the usual installer, but it stopped with a mysterious 2753 error.</p>
  
  <p>How can I proceed with the installation?</p>
