问题
I am using component of Microsoft.Office.Interop.Word.dll on C#.But when i run it on IIS,I am receiving the following error.
Retrieving the COM class factory for component with
CLSID {000209FF-0000-0000-C000-000000000046} failed
due to the following error: 80070005.
if I allow 32-bit applications on IIS,I am receiving the following error.
”Validation of viewstate MAC failed. If this application is
hosted by a Web Farm or cluster,
ensure that <machineKey> configuration specifies the
same validationKey and validation algorithm.
AutoGenerate cannot be used in a cluster”
I am entering the following line into web.config file.
<system.windows.forms jitDebugging="true"/>
if I run again , that's gives me error.
Microsoft Word encountered a problem.
Description: An unhandled exception occurred during the execution
of the current web request. Please review the

where it originated in the code.
Exception Details: System.Runtime.InteropServices.COMException:
Word encountered a problem.
Source Error:
Line 711:
Line 712: //ADDING A NEW DOCUMENT TO THE APPLICATION
Line 713: oWordDoc = oWord.Documents.Add(ref yol, ref oMissing,
ref oFalse, ref oTrue);
Line 714:
Line 715: // SELECT END
By the way, I am using IIS 7 64-bit on Windows Server 2008.
How can i solve this problem?
Thanks in advance.

Error (or HRESULT) 0x80070005 translates to E_ACCESSDENIED which means you've got a permissions problem somewhere.
Make sure your web site's identity has permissions to access Word.
Also make sure your application pool's enable32BitOppOnWin64 setting is configured to match whatever processor architecture your Word app is targeted at.
