How do I return an error from the Init Event of my COM created in VFP?

If i put RETURN .F. in the INIT event, The COM client will receive this error.
OLE error code 0x80004005: Unspecified error.

I have also tried COMRETURNERROR() but i get this error message
Feature is not available.

Any other way to return an error to my COM Client?

Need help on this.

THANKS
