You told so little and just that one thing could have avoided the first question back to you. Think over your posts and try to supply the basics.

i have recently gotten windows 7 and when i try to re-install my hp printer again it goes halfway through installation when it pops up that it cannot continue due to registry keys missing, but i do not know how to fix it nor where to begin. i've looked it up online and it tells me to download this or that and that doesn't work either. i don't know what else to do
