Need DEVELOPR.HLP for Seagate Crystal Reports 6.0 Professional

I have installed Seagate Crystal Reports 6.0 Professional which came bundled with IBM Rational ClearQuest 1.1.

I am after the developer help with use with Visual Basic 6.0 Professional Custom Control.

Therefore I need the DEVELOPR.HLP file for Seagate Crystal Reports 6.0 Professional. This file is used for Development using Seagate Visual Basic Custom Control for use with Visual Basic 6.0.

Any idea where I might get this file from? (I have already tried http://support.businessobjects.com with no luck as I think this version of the product is no longer supported)

Thanks in advance,
Regards,
Richard.
