HP Recommended
Product: HP ENVY Photo 7855 All-in-One Printer
Operating System: Microsoft Windows Vista

Downloaded latest HP ENVY 7800-series Print and Scan device driver and accessories (full pack) and tried to install on Vista.  It failed during step 1 (device driver install) saying that cabinet file E7800x86.cab has an invalid signature.  So I tried the basic package (device driver only) and it failed the same way.

The whole package came down as "unsigned".
