I'm receiving the following error on a Windows XP Pro SP2 x64 machine running IIS6:
System.Runtime.InteropServices.COMException:
Retrieving the COM class factory for component with CLSID
{3C250CBD-6CC9-11D2-9457-00004B48467E} failed due to the following error:
80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
This occurs when trying to instantiate a COM interop object.
Oddly enough, this works fine from a console application running under the same account as the application pool (a user in AD). I.e. both use UserX, so it doesn't seem like an obvious permissions issue.
Anyone else had anything similar?
