title: How do I fix "Fixed invalid Code Analysis ErrorLog file" in log file (reported by SonarQube scanner)?
body: <p>I'm running a SonarSource analysis for a C# project on a Jenkins server. 
  The log shows several of these messages:</p>
  
  <blockquote>
    <p>Fixed invalid Code Analysis ErrorLog file. Please check that VS 2015 Update 1 (or later) is installed.</p>
  </blockquote>
  
  <p>There is no Visual Studio on this Jenkins server. I'm just using MSBuild (14.0.25123.0 - this should be the version you get with VS 2015 Update 2) and "SonarQube scanner for MSBuild 2.0". SonarQube is 5.3, Sonar C# plugin 5.1-RC3</p>
