Unable to find a driver for your systems , Windows 8.1 Asus X550ZE

I have an Asus X550ZE with an integrated R6 and an R7 M265DX ,with windows 8.1 on it.

Today i try to install drivers with Amd Autodetect , but at the end it says Driver not installed and in the register the error message is : unable to find a drive for your system.

The only installation to fail is the one about video drivers.

The OS is fully updated ,i 've also tried to disable firewall and defender and disabling driver firm.

What i can do to install graphics driver ?
