title: Umbraco installation wizard Error - Could not connect to database
body: <p>I'm trying to install Umbraco on an ASP.NET environment. After I downloaded the umbraco nuget package I tried to run the installation wizard, by building and running the project. All is fine and good, if i take the default database configuration, but if I want to customize my configuration, it fails and says :</p>
  
  <blockquote>
    <p>"Could not connect to database"</p>
  </blockquote>
  
  <p>I'm trying to configure it to use my local SQLExpress database, but I just cannot get it working. I have both tried putting in the server information and connecting via. a connection string, via. the wizard. It produces the same error every time.</p>
  
  <p>I have made a database called <strong>umbracoblog</strong> and created an <strong>admin</strong> user, with credentials. He has <strong>dbowner</strong> etc. for the database. Besides that, I have also given full permissions to <strong>IIS_IUSRS</strong> and <strong>Network Service accounts</strong> for the project and all subdirectories, and it still doesn't work. </p>
  
  <p>These are some of the connection strings I have tried:</p>
  
  <pre><code>datalayer=SqlServer;Data Source=.\SQLExpress;Initial Catalog=umbracoblog;User Id=admin;Password=********;
  
  datalayer=SqlServer;Data Source=127.0.0.1\SQLExpress;Initial Catalog=umbracoblog;User Id=admin;Password=*******;
  </code></pre>
  
  <p>I have also tried putting in the connectionstring into the web.config, manually, but that just makes the project load infinitely in the browser, when I run it.</p>
  
  <p>It's starting to get frustrating, that I cannot even get past the configuration of Umbraco, because it look very cool. I have tried everything I was able to found online. Have anyone gone through this and know what I need to do ?</p>
