I haven't seen this yet but this is what info I have been given. Hpzmsi:01 caused an error in Hpzsi01.exe while installing. I believe they are trying to install a HP All In One on a Compaq presario with windows Me. I don't know for sure but it is most likely a USB instillation. I will look at it later. Has anyone had any experience with the All in One. Frank Yahoo!
