apeaking of viruses retro did you get rid of that one that was giving you grief a while ago??

it should install your program, thing is its hp that is not making a driver for windows 7 its their fault not windows, but windows have made its own backwards compatible so these much used brand name devices can still work, thats not to say all will but many will, its not vista that didnt do that to well. it should auto settup down the bottom corner right when you plug it in, it goes searching for it, but you can do a custom windows update and install the latest driver pack from microsoft, if it wasnt included on regular update, try custom update and include the updates you want should work i would think. if you tried using hp's drivers for xp you might have some conflicting problems windows 7 has drivers built in and should do it auto by clicking the right corner when it says device found.
