title: Installing .NET 4.0 on Windows Server 2003 SP2
body: <p>I live in the world of Dark Matter developers where we still have to support mission-critical applications running on Windows Server 2003, SP2, 32 bit.  At least I have the ability to upgrade to .net 4.0 on this machine.  However, when I run the .net 4.0 full installer, I get the error:</p>
  
  <pre><code>Final Result: Installation failed with error code: (0x800B0100), "No signature was present in the subject."
  </code></pre>
  
  <p>Does anyone know how to get this to work?  I have done it on a similar machine, but that was about a year ago.</p>
