In reading this blog my first approach would be some security/rights issues. Has the starting process enough rights to start the app or is it bug. A typo of the UUID and is CLSCTX_LOCAL_SERVER the right flag?

I Have the read the blog it tells about call CoRegisterClassObject but my application is an existing MFC application to which i am adding automation support and i had folllowed the example
http://www.codeproject.com/Articles/8202/Adding-automation-to-MFC-applications.

Is it something to do with calling coregisterclassobject in MFC server application?
i am running the server and client with administrative privilages hence i dont believe having and security issues.
