Manually Registering an ActiveX EXE

I have built an ActiveX EXE and the install package for installing it and registering it. I am looking for a way to register it manually.
The RegSvr32.exe reports an error that the ActiveX EXE is not a DLL or an OCX. I tried RegOCX32.exe and it was silent about its work. I am not really sure if it would really help becuase I checked the registry before and after running regocx32 and there were no changes in the registration.

Any ideas ?

thanks
Arun
