Scanning, Faxing & Copying

I'm running Win7SP1.64bit and trying to install a Scanjet 200 flatbed photo scanner. The installation runs to completion with no error messages but...

Some of the software doesn't appear to have installed correctly, therefore the two desktop shortcuts (HP Scanning and HP Copy) do not work (they both point to hpqkygrp.exe which does not exist on my HDD or on the CD (although it could be in a CAB file somewhere)).

There are no scanner shortcuts at all in my Start menu - only HP Update and a link to IRIS OCR Registration.

All the buttons on the scanner do launch the scan app but it only allows me to scan to picture (JPG, BMP, PNG, TIF). I cannot scan to PDF, scan to email, or scan to printer (copy).

In the scan app, if I click to change the scanner I get the oportunity to change the properties... On the Events tab, I should be able to configure the actions associated with each of the four buttons but the only available "Start this program" action is "Scan". All four buttons are set to this action.

Control Panel -> Programs&Features entries are

    HP Update,

    HP Imaging Device Functions 14.5 and

    OCR Software by I.R.I.S. 14.5.

I've installed and uninstalled the driver and the software numerous times with no difference. I've tried the driver on the CD and downloaded the latest driver from the HP website. I've followed all the troubleshooting procedures I can find but none have helped and i've tried googling this elusive hpqkygrp.exe and found diddlysquat.

I have little enough hair left as it is. Can anyone suggest what might be going wrong?
