Printer driver can not be installed

Envy 7645
Microsoft Windows 10 (64-bit)

I am unable to install driver software for HP Envy 7645. By some reasons I could not print out a couple of weeks ago. I tried most tricks and also unistalled everything in order to reinstall it again. But this time I was not able to install the driver on my Asus laptop. I only get messages like "the device could not be installed by the network". The printer is showed in the network and in "Bluetooth and other devices, but driver is missing". After many hours of search for solution I finally have found this: "Driver is not signed digitally". And that is the driver I have tried to download from HP webpage. I am able to print out from an iPad.


Anyone ho can give me advice of what to do?
