Robert,
Thanks for your reply.
The link you gave is no longer current but I was redirected to another site where I got a contact telephone number. That number did exist but proved to be incorrect because of company changes. Borland, apparently, no longer exists so I had to deal with a company called Embarcadero. The person I spoke to was not able to give help for Delphi issues but gave me another more appropriate company number (both numbers were toll free thankfully). The person I spoke to on the second number said it was possible but complicated to help me directly over the telephone but he was able to give me the web address of the Embarcadero software registration site (**https://support.embarcadero.com/forms/**) from where I was able to email my request for registration help. From then on everything ran very efficiently - I received an initial confirmation of receipt of my email and soon afterwards an email with the registration file I needed. All this happened in less than two hours so excellent service from Embarcadero.
Thanks for your efforts on my behalf, you helped me achieve what I needed in very short time. The issue is now fully resolved.
Best regards, Chris.
