There is no patch; the software is simply too complex.
I have been trying for 9 months to make it work, with a variety of operating systems.
Without exaggeration, I have emailed with HP tech support about this problem at least fifty times. Tried every one of their solutions. I have uninstalled (thorough) and reinstalled dozens of times.
It just doesn't work. at least not with XP and Vista; A few attempts with Windows7 and it PARTIALLY works.
sorry, it's not the answer you wanted but that's been my experience.
