I would appreciate immediate help on this.

We are using a functionality to read and write Excel files using Office
Automation using PIA assemblies for MS Office 2003. We have office 2003
installed on Windows Server 2008.
While trying to run the application we are getting following error -
System.Runtime.InteropServices.COMException
ErrorCode: -2146827284
Message: Exception from HRESULT: 0x800A03EC

The application is running under Network Service account and we have added
this account to Admin group.

Appreciate if some one can help out on this issue at the earliest.

Hi,

Using Excel Automation is not such a good idea cause it's very
complicated to program with it. You should use 3rd party component
like GemBox.Spreadsheet. You will also avoid problems in the future
like if somebody who wants to use your application doesn't have
installed Microsoft Excel he will still be able to use the
application.

I checked on the internet and people have success using Office 2000 and
Office 2003 in IIS with some configuration.
The only thing is it is not working for us because we are missing some thing.
Is there any information any one can point to related this configuration?

This application is using Office 2003 on II6 with no issues for last 3 years
using .Net framework 1.1. The application is now being converted to .Net 2.0
and being ported on 2008 server.

1. Do I need to have Framework 1.1 installed on the 2008 server? We are
using PIA assemblies for excel and on Microsoft site it shows the requirement
of .Net Framework 1.1.

2. My another question is - Do you think using PIA assemblies for Office
2007 will work here if Office 2003 being used on the server.

Doesn't security matter on this server?
