title: Office Interop with 64bit Windows in ASP.NET
body: <p>I'm trying to do office 2003 interop using C# ASP.NET on a server running Windows 2003 64 bit (I'm running IIS in 32bit mode though) and getting error messages like:</p>
  
  <p>The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID 
  {00024500-0000-0000-C000-000000000046} to the user domain\username SID (S-X-X-XX-XXX-XXXX-XXX-XXXXX).  This security permission can be modified using the Component Services administrative tool.</p>
  
  <p>Does anybody know what I need to change to get this working? Thanks if you can help.</p>
  
  <p>EDIT - This was working fine on a 32bit server.</p>
  
  <p>EDIT 2 - Nobody seems to like this but I'm not sure there's any other way given our requirements. If you can think of one, I've opened another question <a href="https://stackoverflow.com/questions/1039451/alternative-to-office-interop-for-document-generation">alternative-to-office-interop-for-document-generation</a></p>
