I remember back when Windows 7 first came out and I got to try out the beta running into my first and much more important driver problem - my (rather ancient C-media) soundcard just would not work and I couldn't get drivers for it for Windows 7 at that time. Somewhere along the way I came across a little program called Driver Max which said it could be used to migrate drivers from one machine or indeed an OS to another so gave it a try. I'm SO glad I did because not only did it immediately solve my soundcard issue, I've since used it as well for this scanner for the same reason - while I could get the scanner installed of sorts it would never run endlessly throwing up error msgs, so the only way of scanning was to go into Devices & doubleclick on it there - not very satisfactory as you can imagine. With Driver Max ideally you need a dual boot system or else ensure that before you fully upgrade to Windows 7 you backup ALL of your important drivers esp for older hardware. Once backed up, install DM in Windows 7 and do a selective restore on those items of hardware you're having problems with. Restart the system and you should be sorted. It's worked for me every time and as I said, I'm so indebted to whoever or whereever I first heard of it. The one time I forgot to try it again after a recent reinstall of Windows 7 I ended up wasting hours upon hours trawling the net vainly trying to find some info on this particular scanner that would enable me to get back to where I had been with it before - working through Picasa without problems. You can download DM though any reputable online download site, esp C-Net.
