title: SharePoint: "Failed to extract the cab file in the solution"
body: <p>I'm receiving a "Failed to extract the cab file in the solution" error when I try to deploy my wsp using stsadm -o addsolution -filename...</p>
  
  <p>I've open the wsp as a cab and checked that there are no duplicate files in there as I understand that can sometimes cause this issue.</p>
  
  <p>The issue only started when I tried to include a custom field type as part of my solution, to do this I added the following to the ddf</p>
  
  <p>..\CustomFields\ShortMonth\ShortMonthControl.ascx ..\CONTROLTEMPLATES\ShortMonthControl.ascx</p>
  
  <p>..\CustomFields\ShortMonth\fldtypes_shortmonth.xml ..\XML\fldtypes_shortmonth.xml</p>
  
  <p>and</p>
  
  <p><code>&lt;TemplateFiles</code>></p>
  
  <p><code>&lt;TemplateFile Location="CONTROLTEMPLATES\ShortMonthControl.ascx"/</code>></p>
  
  <p><code>&lt;TemplateFile Location="XML\fldtypes_shortmonth.xml"/&gt;</code></p>
  
  <p><code>&lt;/TemplateFiles&gt;</code></p>
  
  <p>to the manifest.</p>
  
  <p>I've tried taking it back to just references to the ascx in both but it doesn't see to help.</p>
  
  <p>Any ideas?</p>
