Class not registered 0x80040154

I get a "Class not registered 0x80040154" error when i run my application. My environment setup is windows 2008 using visual studio 2005. I just migrated fr开发者_Python百科om windows xp, where the application used to work with no error. Thanks!

You probably need to register, or "install" a COM server that your application uses.

The dll or exe that provides the interface defined by the CLSID that you are passing to CoCreateInstance either does not exist on your new PC or if it does exist it has not been registered.
