SharePoint 2010 error: Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 800703fa – SharePointWiz

Posted by jpluimers on 2011/04/11

Somehow in a production environment I did get this error too:

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 80040154.

These two posts helped me to solve it:

SharePoint 2010 beta error: Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 800703fa – SharePointWiz – Site Home – MSDN Blogs.

Rhythmic Coding: Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 80040154.

The solution is deceptively simple:

Resolution: It is because you are trying to build a x86 application. Go to project properties and set type to x64 everywhere. Then rebuild and debug. The Error Vanishes!

The SharePoint 2010 dll’s are all x64, and Visual Studio 2010 by default still starts .NET projects in x86 mode for both Release and Debug settings.

      I wish I could help, but I don’t have a SharePoint development environment up and running any more. Please re-ask your question on StackOverflow.com
