Retrieving the COM class factory ......failed due to the following error: 80040154.

Retrieving the COM class factory for component with CLSID .....failed due to the following error: 80040154.

This error occuer when you reference unregistered DLL in your solution.

Solution: Register you dll using regsvr32.exe utility then add the reference again.

> regsvr32 Mydll.dll /u --For unregister
> regsvr32 Mydll.dll --For register

Hope this will help

How do i find out which dll it is that CLSID {0006F03A-0000-0000-C000-000000000046} refers to ??

to find the dll from CLSID go to the Registry Eidtor.(Run regedit)
In Registry Eidtor on left pan u will get details of all CLSID under:----

I am having the same problem too. I tried registering the dll and it says now "The module "" was loaded but the entry-point DllRegisterServer was not found.
Make sure that "" is a valid DLL or OCX file and then try again". What do I do? I have Outlook 2007 not 2003. Could that also be the problem? my boss said that could be the problem too.thanks
