Having upgraded my Aunt's PC to Windows 7 Professional 32-bit over Christmas, I'd asked her to test and report back.

There were a few things left to do, including installing Irfanview and sorting out the drivers for the Nvidia video card.
However, there was one thing that bugged me for most of this afternoon.
Whenever she attempted to insert a scanned image into a Microsoft Word 2000 document, she got: -
Unable to connect to scanner or camera. Check the connection and reinstall driver if necessary
even though the scanner ( in fact, TWO scanners; a Canoscan 8800F and a HP Deskjet 3055A ) worked perfectly outside of Word.
After much Googling and a fair bit of fiddling and faffing, I realised that, if I ran Word as Administrator, the scanner integration worked perfectly.
Long story short, the problem was NOT related to the Canon drivers ( in fact, I reinstalled them ! ), the USB cables betwixt PC and scanners, Word 2000 or the Windows Image Acquisition service.
For some reason, Word 2000 can only see the scanner ( using, I believe, the TWAIN drivers via c:\windows\twain_32 ) *IF* Word is run as Administrator.
I ended up creating a little batch file to make use of the runas command. This allows Word to be started as Administrator from a short-cut on the desktop.
However, the good news is that it now works.
For my next trick, I need to work out how to add a short-cut to the batch file into the Quick Launch task bar at the bottom of the screen.
