  <p>This error means that Windows does not recognize the input file as something it is able to affix a digital signature on.</p>
  
  <p><strong>Possible workaround</strong></p>
  
  <p>Using <strong>SetReg.exe</strong> <a href="http://msdn.microsoft.com/en-us/library/7zaf80x7(v=vs.80).aspx" rel="noreferrer">Set Registry Tool</a> to disable Certificate Revocation List checking.   </p>

  <p>I can try the workaround above to sort the problem, but i was in belief that VS 2013 RC can be easily updated?</p>
  
  <blockquote>
    <p>VS 2013 can be installed side by side with previous versions of Visual
    Studio or, if you have a VS 2013 pre-release, it can be installed
    straight over  top of the pre-release.</p>

  <p><strong>UPDATE</strong></p>
  
  <p>I've tried using web installer or downloading ISO image again, with no success, as possible solutions in related sources.</p>
