title: "Failed to initialize the Common Language Runtime" when trying to access a SQL 2014 Express database
body: <p>I'm currently developing a website that <a href="http://grammarpartyblog.com/2012/01/17/use-versus-utilize/" rel="nofollow">uses</a> a SQL Server 2014 Express database on my machine. This has always worked in the past, but today I got the following error:</p>
  
  <blockquote>
    <p>Failed to initialize the Common Language Runtime (CLR) v4.0.30319 with
    HRESULT 0x80131534. You need to restart SQL Server to use CLR
    integration features.</p>
  </blockquote>
  
  <p>Of course I restarted SQL Server 2014 Express, but to no avail.</p>
