title: Value error trying to install Python for Windows extensions
body: <p>I have Microsoft Visual Studio 2008 installed already. I downloaded the zip file <a href="http://sourceforge.net/tracker/index.php?func=detail&amp;aid=3083722&amp;group_id=78018&amp;atid=551954" rel="noreferrer">Python for Windows extensions</a> and extracted the contents into my Python27 folder. There's now a subfolder called pywin32-214. (Is the 32 part a problem? I'm on a 64-bit system.) Here's a transcript from the command line:</p>
  
  <pre><code>C:\Python27\pywin32-214&gt;setup.py -q install
  Building pywin32 2.7.214.0

  <p>I don't know what to make of this. Help?</p>
