title: WIA Scanning issues on XP
body: <p>I have a WPF application that I am using to scan documents to a users mailbox etc.</p>
  
  <p>When debugging the application on my 32bit Windows 7 professional machine all goes according to plan, as well as the deployed version on another 32bit Windows 7 machine.</p>
  
  <p>When I deploy to a XP machine and try to start a scan I get the following error:</p>
  
  <blockquote>
    <p>Retrieving the COM class factory for component with CLSID
    {850D1D11-70F3-4BE5-9A11-77AA6B2BB201} failed due to the following
    error: 80040154 Class not registered (Exception from HRESULT:
    0x80040154 (REGDB_E_CLASSNOTREG)).</p>
  </blockquote>
  
  <p>Any suggestions?</p>
