I find that the new ones are too bloated with Wattman etc installed
i now use Overdriventool, much better and works fine.
You can always extract the bundle (using 7Zip or WinZip) and simply point Windows to the Packages\Drivers\Display folder when installing a new device, or do a Custom Install and unselect AMD Settings.
As you've already done, use OverdriveNTool for AMD cards.
