HI,
I have the same problem with my Photosmart C7180 All-in-one on Windows 8.1
The enitial problem was the software wouldn't open to run the scanner after the upgrade from Windows 8. The solution was to uninstall, reboot and re-install the HP Photosmart Full Feature Software and Drivers
I even treid with the install wizard.
Now I get the same message and am unable to re-install. Great not only can i not use my scanner, I can now also not use the printer!!!!
The help option file in the install window is also not found!
I have tried a nummber of "solutions" and none of them have worked!
