title: Sitecore 7 WFFM Could not load file or assembly 'HtmlAgilityPack, Version=1.4.0.0
body: <p>I'm upgrading a website from Sitecore 6.5 to Sitecore 7. The upgrade has been smooth and I was able to get everything up and running except for WFFM.</p>
  
  <p>After installing WFFM 2.3 latest, I keep getting the error</p>
  
  <blockquote>
    <p>Could not load file or assembly 'HtmlAgilityPack, Version=1.4.0.0,
    Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' or one of its
    dependencies. The located assembly's manifest definition does not
    match the assembly reference. (Exception from HRESULT: 0x80131040)</p>
  </blockquote>
  
  <p>Sitecore 7 upgrades it's 3rd party dll for HtmlAgilityPack to 1.4.3, but WFFM seems to still reference 1.4.0</p>
  
  <p>Has anyone dealt with this? Am I missing something?</p>
  
  <p>Thanks for the help.</p>
