Retrieving the COM class factory.... Error Message

Hi,

I try to create an appointment in the user calendar from aspx page with the following code :

Imports Microsoft.Office.Interop.Outlook

Dim objOutlook As New Application

Dim objOutlookAppt As MailItem

objOutlookAppt = objOutlook.CreateItem(OlItemType.olMailItem)

With objOutlookAppt

.Subject = "test"

.To = "gregory.schneider@kpmg.lu"

.Send()

End With

But I've always the same message :

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80040154.

Re: Retrieving the COM class factory.... Error Message

I'm Having the same problem but i'm using another dll, i don´t know in which language it was written, i just added the reference to it and it created the Interop and when i try to instantiate the class i get that error, here is my code

[WebMethod]
    public bool validaUsuario()
    {
        try
        {
            //procesosClass proc = new procesosClass();
            ManagedSAIBL.procesosClass proc = new ManagedSAIBL.procesosClass(); // HERE IT CRASHES and gives me the same error that you get

            proc.PATH = @"C:\websites\ecommercesaicom\ecommerce\demo\db";
            proc.PASSWORD = "admin";

            return proc.ACCESSUSER.ToString().Equals("1") ? true : false;
        }
        catch (Exception ex)
        {
            ex.Message.ToString();
            return false;

Re: Retrieving the COM class factory.... Error Message

I am having the same problem but I dont have Ms office installed on server system

can I still use Interop.Excel assembly for reading excel files.

Re: Retrieving the COM class factory.... Error Message

This Error is most likely caused by trying to do Excel Automation (32-bit) on a 64-bit Operating System.

I tried to see if it was possible to create a 32-bit App Pool to run the website under, but that still doesn't seem to work.

The only solution I have found so far is to convert my ASP.NET Website to an ASP.NET Web Application and then in the Project properties explcitly set the Target CPU Platform from "Any" to "x86".

@rizwanahmed23

No, the Interop dlls are only proxys, you still need Excel installed on the Web Server.

You also need to run DCOMCNFG.EXE and give the ASP Worker Proccess (or App Pool account) Launch and Activation permissions on the Excel.Application object.
