PS to my post this afternoon.
I have just successfully (and uneventfully) installed the same CS3 download on my wife's XP machine, so there is no problem with serial no. And I should have said that there is no history of CS3 on this machine, it is all running on a newly-formated hard drive less thatn three weeks old.
Whatever Vallen and his colleague say at Adobe, this seems to be a Windows 7 issue, because this Dell Precision 390 has for three years successfully run CS3.
It would be inconvenient to uninstall Photoshop Elements 10 because that is now fully integrated with the HP scanner, so I am hoping one of you gents will come up with an alternative way through.

I don't see any problem here. It's just using the standard TWAIN or WIA interfaces. There's no magic custom code in any of the Adobe apps regarding support for specific scanners, cameras or whatever. At worst you may lose color calibration and some presets.
I had onscreen chats with Adobe's Vallen and (maybe) Sumar, who just sent me back to the Support page and forum page. Digging there I eventually found http://kb2.adobe.com/cps/401/kb401531.html and followed the instructions, including deleting the caps folder because neither of the database files were in it.
Not sure what you are trying to say by that. without any of the files neitehr Adobe apps would ever work or install correctly, so they must be somewhere. If they are not in the proper folder, then maybe they have ended up elsewhere due to permission issues or compatibility problems. CS3 is, after all, unsupported on Win7. This may even be some silly issue in your Win7 install which now may include some patches that didn't exist 3 years ago and it affects security policies. In any case do some digging. And yes, it may help to install in order and get rid of PSE 10. A newer product could introduce incompatible data into the installer database that legacy products cannot handle correctly...
The files referred to from memory were……\program files\common files\adobe\caps\caps.dbf and …..\adobe\backup\caps.dbf. There were two other files in the first of these folders, so the advice seemed to be to delete the folder which I did, maybe not meant to?
Re- compatibility, I asked the second chat-room guy if CS3 was compatible with Win7, which MS had claimed before I installed, and he said yes. I think you are saying that PS Elements 10 needs to be installed after CS3, but I’ll give the world a little time before I do that in case a more elegant fix comes up.
Good to have feedback.
In case it helps anyone else, the solution (as both Mylenium and I had suspected) was to uninstall Photoshop Elements 10.
I progressively uninstalled all Adobe progs, leaving PSE 10 to last for emphasis, and only at that point did the installation become possible. So thanks all for your patience. - TomBrikar
