That's the main problem.
I remeber i fixed this problem months ago by installing a patch made by AMD, but i can't find it. (I tried all the suggestion made by AMD, and nothing else worked)
The error is "No AMD graphics driver is installed..."
Specs: Win10 PRO 64bits Version: 1930
GPU: RX470
CPU: i5 4460

Thanks beforehand!
