Question Word Automation issue in ASP.Net 2.0 in IIS 6.0 64 bit mode, Windows server 2003

[Kiran Beladiya]

I've the Word Automation problem in my asp.net 2.0 website.. I've applied all the proposed solutions so far to give rights in DCOMCNFG.

I have asp.net 2.0 web application running on
-Windows server 2003 64 bit version
-IIS 6.0 64-bit
-Microsoft Office 2007

I am doing simple mail merge using WORD com object, I've given rights to all the keys bellow in DCOMCNFG:
{000209FE-0000-0000-C000-000000000046}
{000209FF-0000-0000-C000-000000000046}
{00020906-0000-0000-C000-000000000046}

tried to give full rights to Network Service, Interective User and Finally Everyone. Also tried with 'interactive user' as well 'launching user'. But I am still getting the same error of access denied. The exact errormessage is as bellow:

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80080005.

OR

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 8000401a.

The strange thing is, when i run the same code in a test windows application on that server, it works fine!

Does anybody have solution that work with IIS 6.0 64-bit too?
