title: Installing Composer on IIS 7.5
body: <p>I'm trying to install Composer on IIS 7.5. When I run Composer-Setup.exe, it fails with:</p>
  
  <blockquote>
    <p>The PHP exe file you specified did not execute correctly:  C:\Program
    Files (x86)\PHP\php.exe</p>
    
    <p>Running it from the command line might highlight the problem. Use the
    -v switch to show the PHP version - it must be at least 5.3.2 Internal Error [ERR_STATUS], exit code 255</p>
  </blockquote>
  
  <p>I'm using PHP 5.6.9, so then I run the following bash:</p>
  
  <pre><code>$ php -r "readfile('https://getcomposer.org/installer');" | php
  #!/usr/bin/env php 
  All settings correct for using Composer
  </code></pre>
  
  <p>There are no errors, but it doesn't download. Using SSL or not makes no difference. </p>
  
  <p>Using cURL gives the same result:</p>
  
  <pre><code>$ curl -s https://getcomposer.org/installer | php
  #!/usr/bin/env php 
  All settings correct for using Composer
  </code></pre>
  
  <p>I'd be grateful for any troubleshooting suggestions!</p>
