nothing - had a window pop up with " Unable to start this driver
a splash screen warning displayed on startup after installing the drivers for hp7550 - Zone Labs Security Suite was running at the time.
For HP printers
This file is supposed to be connected to the HP Photosmart Printer but I cant figure out why it keeps popping up
This file is needed to install the HP Photo smart Card Reader
There are two separate files on my computer with this name. One is in the printer's program file, the other is in System32. To my understanding, the one in System32 is the one causing the ruckus (Unable to start this driver). So all I need to do is delete it?
Definitely a conflict between Zone Alarm and HP photosmart card reader driver. Giving PML full 'ALLOW' in ZA didn't fix it for me.

HP 7150 printer driver
I have this process stopped, which prevents me from printing on an HP7350 printer, with an error "unable to start HPHipm11.exe" Consequently, I think it's necessary for certain printers.
I got an error about this after I hooked up and hp printer and then unhooked it and rebooted
I just started getting this error. After reading comments and forgettting which printer I had, checked and discovered i too have HP and it is a photosmart printer. What puzzles me is, why is this error only popping up now? the only thing i have installed recently is a newer version of PC tools SPYWARE doctor. Could this be related?
The error message may display every time the computer is started, or only occasionally. After closing the error message, the printer may or may not print and allow access to the card reader properly.

I reinstalled HP printer driver and it went away

It pops up three times in a row when I try to print. After that I can print okay.
