title: Cannot execute a javascript script file from windows explorer or the DOS prompt
body: <p>I'm a C++ developer and want to install the WTL appwizard to Visual Studio 2010.  To do this, I must run a .js script file.  </p>
  
  <p>I recently tried out Aptana IDE and it's clobbered the .js file association, and now I cannot execute this .js script file.</p>
  
  <p>How can I execute .js script files again?</p>
