title: Cannot find vcvarsall.bat when running a Python script
body: <p>I am working on Vista, and using Python 2.6.4. I am using a software that utilizes a Python script, but bumped into the message:</p>
  
  <pre><code>cannot find vcvarsall.bat
  </code></pre>
  
  <p>So, I installed visual c++ 2010. Still the file is not found - though, it is there. My guess (a very uneducated one...) is that somewhere the path is wrong, because I also have an old visual 2008 (pretty empty) folder. I have no idea where to make the changes for the new path. Do I change something in the registry or in the script? Or somewhere else?</p>
