I am running Windows 8.1 Pro.
I have tried to install the software and drivers for HP OfficeJet Pro 8600 without any success.
I have tried removing the software, reinstalling, restarting the computer, doing a "clean" boot, and nothing has worked so far.
I have received the following message error:
A file that is required cannot be installed because the cabinet file c:\users\User\appdata\local\temp\7zS2EAD\OJ860x64.cab has an invalid digital signature. This may indicate that the cabinet file is corrupt.
The message error is the same every time I try something new.
I am able to print, if I add the printer thru the "Add Printer" option in Windows explorer, but I want to install the full software so that I can also scan.
I have downloaded more than 10 times the several files associated with troubleshooting: Troubleshooting HP Installation Failure MSI, HP Print and Scan Doctor, but they have not helped at all.
Any suggestions would be greatly appreciated.
