title: WIA services 2, download and install on windows xp / 7
body: <p>I've written a application that scans images from a scanner.
  this works fine on my development machine (win7 ultimate sp1 64bit).</p>
  
  <p>i've tried to run the app on a windows xp machine (or windows server 2008 standard) and it failed with this error</p>
  
  <blockquote>
    <p>System.Runtime.InteropServices.COMException (0x80040154): Retrieving
    the COM class factory for component with CLSID
    {E1C5D730-7E97-4D8A-9E42-BBAE87C2059F} failed due to the following
    error: 80040154 Class not registered (Exception from HRESULT:
    0x80040154 (REGDB_E_CLASSNOTREG)).</p>
  </blockquote>
  
  <p>it seems that the machines are missing the WIA dlls.</p>
  
  <p>when looking around microsoft site for the installation files, i've failed to find them.</p>
  
  <p>so my question are, 
  where can i find the installation files ? 
  and can i install WIA 2 on XP?</p>
