  </code></pre>
  
  <p>I am Windows 10 and have Visual Studio 2017 installed.
  I'm thinking the problem could be I installed SQL Server Management Studio 2017 before I installed SQL Server.</p>
  
  <p>I have the same setup at home but I installed SQL Server first and then SSMS and everything works fine.</p>
  
  <p>The other difference is at home in the installation dialog it says something the affect that C++ Redistribuble is already installed but at  work where it is failing it says it is to be installed in hte list of components.</p>
