Localdb in Visual Studio 2015 error 52 (SQL Server)
<p>I programmed an application with an attached <code>.mdf</code> database file that works fine on my computer. But on another computer (client PC) I get this error message :</p>

<blockquote>
  <p>A network-related or instance-specific error occurred while
  establishing a connection to SQL Server. The server was not found or
  was not accessible. Verify that the instance name is correct and that
  SQL Server is configured to allow remote connections. (provider: SQL
  Network Interfaces, error: 52 - Unable to locate a Local Database
  Runtime installation. Verify that SQL Server Express is properly
  installed and that the Local Database Runtime feature is enabled.)]
  System.Data.SqlClient.SqlInternalConnection</p>
</blockquote>

<p>Should I install SQL Server Express on my client PC? It's just impossible, can you please help ? </p>

<p>Thanks in advance</p>
