title: Fail configuration of MySQL server installation
body: <p>I was trying to reinstall MySQLServer on my local machine (Win7 32), using Windows (x86, 32-bit), MSI Installer.</p>
  
  <p>When wizard configure server, after installation, gives the error "Configuration failed", with details:</p>
  
  <pre><code>mysql-server-5.5-win32:6 - Looking for valid template
  mysql-server-5.5-win32:13 - Found valid template.
  mysql-server-5.5-win32:20 - Attempting to process template.
  mysql-server-5.5-win32:26 - Processed template.
  mysql-server-5.5-win32:33 - Attempting to configure service.
  mysql-server-5.5-win32:40 - Configured service.
  mysql-server-5.5-win32:46 - Attempting to start service.
  mysql-server-5.5-win32:100 - Unable to configure service.
  mysql-server-5.5-win32:100 - Product configuration controller finished configuration.
  </code></pre>
  
  <p>Why does it happen?</p>
  
  <p>Can it result from using a wrong "old" password that I put in the installation wizard, to set a new password? If yes - How can I clean up ALL previous settings of MySQL server?</p>
