title: Cannot start a service instance in Virtuoso-opensource
body: <p>I'm trying to create and start the service instance. But it doesn't start.
  Here is the command I ran:</p>
  
  <pre><code>virtuoso-t +service start +instance MyService
  </code></pre>
  
  <p>Here my output:</p>
  
  <pre><code>The Virtuoso_MyService service is being started
  </code></pre>
  
  <p>But the <code>localhost:8890</code> cannot be loaded.</p>
  
  <p><strong>Details:</strong></p>
  
  <ul>
  <li>Opened CMD as administrator.</li>
  <li>Ran the same commands 3 days back and the services were running fine till I restarted the system.</li>
  <li><p>Commands followed.</p>
  
  <pre><code>C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\bin&gt;virtuoso-t +service create +instance MyService +configfile ..\database\virtuoso.ini
  
  [Using virtuoso.ini in C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\database]
  The Virtuoso_MyService service has been registered
    and is associated with the executable 
  
  C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\bin\virtuoso-t.exe

  16:27:37 This probably means you either do not have permission to start
  16:27:37 this server, or that virtuoso-t is already running.
  16:27:37 If you are absolutely sure that this is not the case, please try
  16:27:37 to remove the file virtuoso.lck and start again.
