  <p>I looked at the event viewer and I saw the following:</p>
  
  <p><em>Crypt32 Error, Event ID 11
  Description: Failed extract of third-party root list from auto update cab at: <a href="http://www.download.windowsupdate.com/msdownloadupdate/v3/static/trustdr/en/authrootstl.cab" rel="nofollow noreferrer">http://www.download.windowsupdate.com/msdownloadupdate/v3/static/trustdr/en/authrootstl.cab</a> with error: The data is invalid.</em></p>
  
  <p>I'm not sure what's going on here but I'm guessing it's something to do with the digitally signed key in FC.MrsCore that "encountered a problem" and something to with certificates no doubt.  In any case can anyone shed any light on what is going on here and how I can sort it.</p>
  
  <p>I have installed this program on other PC's fine it's just this one PC that seems to be causing me some problems.</p>
