ERROR 429, ActiveX can't create object

Hi.
I have a problem of AutoEmail with Outlook Demonstration Project.
http://vb-world.net/demos/autoemail/
I am getting error which says:
"Runtime Error 429"
"ActiveX component can't create object"
when I try to activate program.
I believe this is because AutoEmail.exe is not registered.
So I have tried to register under RUN.(regsvr32 "C\Mydir\AutoEmail.exe")
However, the program still gives me a following error.
c:\mydir\AutoEmail.exe was loaded but the dllRegisterServer entry point was not found
c:\mydir\AutoEmail.exe does not appear to be a .DLL or .OCX file

I would like you to help me how to run this AutoEmail sample.
Thank you very much.

That error indicates that you compiled using a different version of a DLL or OCX then what the program is trying to use at run time.

REGSVR32 only works with DLLs and OCXs and the like. It doesn't work with EXEs.

You need to make sure that the References in the Project menu are all registered and that they are the ones being used by the system.
