  Microsoft.Office.Interop.Excel

  Nov 10, 2011 04:37 PM|LINK

  i have developed an application that uses Microsoft.Office.Interop.Excel it works locally. but on the server i get the error

  Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

  any ideas

  what do i need to register on the server for this to work

  note excel is not installed on the server is it  needed?

  i wouldnt have thought so.

  Of course it is needed! It is COM, not .Net Install under a user and put the site app pool run under same user

  Did you ever get a resolution?  I, too, am having this same issue.  Does Excel need to be installed or were you able to simply register a .dll on the server for this to work?
